Update the port of FreeBSD to Cavium Octeon to use the Cavium Simple Executive
library:
o) Increase inline unit / large function growth limits for MIPS to accommodate
the needs of the Simple Executive, which uses a shocking amount of inlining.
o) Remove TARGET_OCTEON and use CPU_CNMIPS to do things required by cnMIPS and
the Octeon SoC.
o) Add OCTEON_VENDOR_LANNER to use Lanner's allocation of vendor-specific
board numbers, specifically to support the MR320.
o) Add OCTEON_BOARD_CAPK_0100ND to hard-wire configuration for the CAPK-0100nd,
which improperly uses an evaluation board's board number and breaks board
detection at runtime. This board is sold by Portwell as the CAM-0100.
o) Add support for the RTC available on some Octeon boards.
o) Add support for the Octeon PCI bus. Note that rman_[sg]et_virtual for IO
ports can not work unless building for n64.
o) Clean up the CompactFlash driver to use Simple Executive macros and
structures where possible (it would be advisable to use the Simple Executive
API to set the PIO mode, too, but that is not done presently.) Also use
structures from FreeBSD's ATA layer rather than structures copied from
Linux.
o) Print available Octeon SoC features on boot.
o) Add support for the Octeon timecounter.
o) Use the Simple Executive's routines rather than local copies for doing reads
and writes to 64-bit addresses and use its macros for various device
addresses rather than using local copies.
o) Rename octeon_board_real to octeon_is_simulation to reduce differences with
Cavium-provided code originally written for Linux. Also make it use the
same simplified test that the Simple Executive and Linux both use rather
than our complex one.
o) Add support for the Octeon CIU, which is the main interrupt unit, as a bus
to use normal interrupt allocation and setup routines.
o) Use the Simple Executive's bootmem facility to allocate physical memory for
the kernel, rather than assuming we know which addresses we can steal.
NB: This may reduce the amount of RAM the kernel reports you as having if
you are leaving large temporary allocations made by U-Boot allocated
when starting FreeBSD.
o) Add a port of the Cavium-provided Ethernet driver for Linux. This changes
Ethernet interface naming from rgmxN to octeN. The new driver has vast
improvements over the old one, both in performance and functionality, but
does still have some features which have not been ported entirely and there
may be unimplemented code that can be hit in everyday use. I will make
every effort to correct those as they are reported.
o) Support loading the kernel on non-contiguous cores.
o) Add very conservative support for harvesting randomness from the Octeon
random number device.
o) Turn SMP on by default.
o) Clean up the style of the Octeon kernel configurations a little and make
them compile with -march=octeon.
o) Add support for the Lanner MR320 and the CAPK-0100nd to the Simple
Executive.
o) Modify the Simple Executive to build on FreeBSD and to build without
executive-config.h or cvmx-config.h. In the future we may want to
revert part of these changes and supply executive-config.h and
cvmx-config.h and access to the options contained in those files via
kernel configuration files.
o) Modify the Simple Executive USB routines to support getting and setting
of the USB PID.

Add support for True IDE mode to the Octeon CF driver. This mode is
signalled when the attribute address for the CF is 0 in the octeon
sysinfo structure. In this mode, the DATA port is 16-bits, but the
other ports are 8-bits, but on a 16-bit bus (so you have to access it
a short at a time, but only believe the lower byte). See the code for
more details on this slightly odd arrangement. I'm still not 100%
happy with the abstractions here on many levels (starting with the
globals for these settings, on down to no bus_space use, etc), but the
driver had these problems before the change.
Also, clean up the code a bit to make this support easier, and the
code a bit easier to read. I tried to follow existing style, but may
have missed a few spots. Add some comments.
Fix probe/attach routine to return a proper error for the simulator.
With this change, my EBH5200 eval board now recognizes the CF well
enough to boot to the login prompt. Before it would say it never
became ready. My CN3010-EVB-HS5 still boots properly. My older
CN3860-based board won't load the 64-bit kernel, either before or
after the change, and I didn't chase that down.

/*

* There's three bus types supported by this driver.
|
|
|
|
|
*
|
|
|
|
|
* CF_8 -- Traditional PC Card IDE interface on an 8-bit wide bus. We assume
|
|
|
|
|
* the bool loader has configure attribute memory properly. We then access
|
|
|
|
|
* the device like old-school 8-bit IDE card (which is all a traditional PC Card
|
|
|
|
|
* interface really is).
|
|
|
|
|
* CF_16 -- Traditional PC Card IDE interface on a 16-bit wide bus. Registers on
|
|
|
|
|
* this bus are 16-bits wide too. When accessing registers in the task file, you
|
|
|
|
|
* have to do it in 16-bit chunks, and worry about masking out what you don't want
|
|
|
|
|
* or ORing together the traditional 8-bit values. We assume the bootloader does
|
|
|
|
|
* the right attribute memory initialization dance.
|
|
|
|
|
* CF_TRUE_IDE_8 - CF Card wired to True IDE mode. There's no Attribute memory
|
|
|
|
|
* space at all. Instead all the traditional 8-bit registers are there, but
|
|
|
|
|
* on a 16-bit bus where addr0 isn't wired. This means we need to read/write them
|
|
|
|
|
* 16-bit chunks, but only the lower 8 bits are valid. We do not (and can not)
|
|
|
|
|
* access this like CF_16 with the comingled registers. Yet we can't access
|
|
|
|
|
* this like CF_8 because of the register offset. Except the TF_DATA register
|
|
|
|
|
* appears to be full width?

Add support for True IDE mode to the Octeon CF driver. This mode is
signalled when the attribute address for the CF is 0 in the octeon
sysinfo structure. In this mode, the DATA port is 16-bits, but the
other ports are 8-bits, but on a 16-bit bus (so you have to access it
a short at a time, but only believe the lower byte). See the code for
more details on this slightly odd arrangement. I'm still not 100%
happy with the abstractions here on many levels (starting with the
globals for these settings, on down to no bus_space use, etc), but the
driver had these problems before the change.
Also, clean up the code a bit to make this support easier, and the
code a bit easier to read. I tried to follow existing style, but may
have missed a few spots. Add some comments.
Fix probe/attach routine to return a proper error for the simulator.
With this change, my EBH5200 eval board now recognizes the CF well
enough to boot to the login prompt. Before it would say it never
became ready. My CN3010-EVB-HS5 still boots properly. My older
CN3860-based board won't load the 64-bit kernel, either before or
after the change, and I didn't chase that down.

Add support for True IDE mode to the Octeon CF driver. This mode is
signalled when the attribute address for the CF is 0 in the octeon
sysinfo structure. In this mode, the DATA port is 16-bits, but the
other ports are 8-bits, but on a 16-bit bus (so you have to access it
a short at a time, but only believe the lower byte). See the code for
more details on this slightly odd arrangement. I'm still not 100%
happy with the abstractions here on many levels (starting with the
globals for these settings, on down to no bus_space use, etc), but the
driver had these problems before the change.
Also, clean up the code a bit to make this support easier, and the
code a bit easier to read. I tried to follow existing style, but may
have missed a few spots. Add some comments.

Add support for True IDE mode to the Octeon CF driver. This mode is
signalled when the attribute address for the CF is 0 in the octeon
sysinfo structure. In this mode, the DATA port is 16-bits, but the
other ports are 8-bits, but on a 16-bit bus (so you have to access it
a short at a time, but only believe the lower byte). See the code for
more details on this slightly odd arrangement. I'm still not 100%
happy with the abstractions here on many levels (starting with the
globals for these settings, on down to no bus_space use, etc), but the
driver had these problems before the change.
Also, clean up the code a bit to make this support easier, and the
code a bit easier to read. I tried to follow existing style, but may
have missed a few spots. Add some comments.
Fix probe/attach routine to return a proper error for the simulator.
With this change, my EBH5200 eval board now recognizes the CF well
enough to boot to the login prompt. Before it would say it never
became ready. My CN3010-EVB-HS5 still boots properly. My older
CN3860-based board won't load the 64-bit kernel, either before or
after the change, and I didn't chase that down.

Update the port of FreeBSD to Cavium Octeon to use the Cavium Simple Executive
library:
o) Increase inline unit / large function growth limits for MIPS to accommodate
the needs of the Simple Executive, which uses a shocking amount of inlining.
o) Remove TARGET_OCTEON and use CPU_CNMIPS to do things required by cnMIPS and
the Octeon SoC.
o) Add OCTEON_VENDOR_LANNER to use Lanner's allocation of vendor-specific
board numbers, specifically to support the MR320.
o) Add OCTEON_BOARD_CAPK_0100ND to hard-wire configuration for the CAPK-0100nd,
which improperly uses an evaluation board's board number and breaks board
detection at runtime. This board is sold by Portwell as the CAM-0100.
o) Add support for the RTC available on some Octeon boards.
o) Add support for the Octeon PCI bus. Note that rman_[sg]et_virtual for IO
ports can not work unless building for n64.
o) Clean up the CompactFlash driver to use Simple Executive macros and
structures where possible (it would be advisable to use the Simple Executive
API to set the PIO mode, too, but that is not done presently.) Also use
structures from FreeBSD's ATA layer rather than structures copied from
Linux.
o) Print available Octeon SoC features on boot.
o) Add support for the Octeon timecounter.
o) Use the Simple Executive's routines rather than local copies for doing reads
and writes to 64-bit addresses and use its macros for various device
addresses rather than using local copies.
o) Rename octeon_board_real to octeon_is_simulation to reduce differences with
Cavium-provided code originally written for Linux. Also make it use the
same simplified test that the Simple Executive and Linux both use rather
than our complex one.
o) Add support for the Octeon CIU, which is the main interrupt unit, as a bus
to use normal interrupt allocation and setup routines.
o) Use the Simple Executive's bootmem facility to allocate physical memory for
the kernel, rather than assuming we know which addresses we can steal.
NB: This may reduce the amount of RAM the kernel reports you as having if
you are leaving large temporary allocations made by U-Boot allocated
when starting FreeBSD.
o) Add a port of the Cavium-provided Ethernet driver for Linux. This changes
Ethernet interface naming from rgmxN to octeN. The new driver has vast
improvements over the old one, both in performance and functionality, but
does still have some features which have not been ported entirely and there
may be unimplemented code that can be hit in everyday use. I will make
every effort to correct those as they are reported.
o) Support loading the kernel on non-contiguous cores.
o) Add very conservative support for harvesting randomness from the Octeon
random number device.
o) Turn SMP on by default.
o) Clean up the style of the Octeon kernel configurations a little and make
them compile with -march=octeon.
o) Add support for the Lanner MR320 and the CAPK-0100nd to the Simple
Executive.
o) Modify the Simple Executive to build on FreeBSD and to build without
executive-config.h or cvmx-config.h. In the future we may want to
revert part of these changes and supply executive-config.h and
cvmx-config.h and access to the options contained in those files via
kernel configuration files.
o) Modify the Simple Executive USB routines to support getting and setting
of the USB PID.

Add support for True IDE mode to the Octeon CF driver. This mode is
signalled when the attribute address for the CF is 0 in the octeon
sysinfo structure. In this mode, the DATA port is 16-bits, but the
other ports are 8-bits, but on a 16-bit bus (so you have to access it
a short at a time, but only believe the lower byte). See the code for
more details on this slightly odd arrangement. I'm still not 100%
happy with the abstractions here on many levels (starting with the
globals for these settings, on down to no bus_space use, etc), but the
driver had these problems before the change.
Also, clean up the code a bit to make this support easier, and the
code a bit easier to read. I tried to follow existing style, but may
have missed a few spots. Add some comments.
Fix probe/attach routine to return a proper error for the simulator.
With this change, my EBH5200 eval board now recognizes the CF well
enough to boot to the login prompt. Before it would say it never
became ready. My CN3010-EVB-HS5 still boots properly. My older
CN3860-based board won't load the 64-bit kernel, either before or
after the change, and I didn't chase that down.
