while doing the block store workaround so we restore the correct
floating-point registers state in case of nested floating-point

VIS-based block copy/zero functions to be used on machines

saving the floating-point registers here, which would be more
inefficiently though and also involves turning off interrupts.

SCZ_PCI_DMA_SYNC can't be used as intended either, so remove

- Apply 4 bytes alignment limitation of Tx buffer.
- Apply 8 bytes alignment limitation of Rx buffer.
- Tx side bus_dmamap_load_mbuf_sg(9) support.
- Preallocate Tx DMA maps as creating DMA maps take very long time

- Adjust guard buffer size to 1522 + 8 as it should include VLAN

- Plug memory leak in device detach. Previously wrong buffer

- Added rl_list_rx_init() to clear Rx buffer and cleared the

- Don't destroy DMA maps in rl_txeof() as the DMA map should be
reused. There is no reason to destroy/recreate the DMA maps in
this driver.
- Removed rl_dma_map_rxbuf()/rl_dma_map_txbuf() callbacks.
- The hardware does not support descriptor based DMA on Tx side
and the Tx buffer address should be aligned on 4 bytes boundary
as well as manual padding for short frames. Because of this
hardware limitation rl(4) always used to invoke m_defrag(9) to
get a 4 bytes aligned single buffer. However m_defrag(9) takes
a lot of CPU cycles on slow machines and not all packets need
the help of m_defrag(9). Armed with the information, don't
invoke m_defrag(9) if the following conditions are true.
1. Buffer is not fragmented.
2. Buffer is aligned on 4 bytes boundary.
3. Manual padding is not necessary.
4. Or padding is necessary but upper stack passed a writable
buffer and the space needed for padding is satisfied.
This change combined with preallocated DMA maps greatly
increased Tx performance of driver on sparc64.
- Moved bus_dmamap_sync(9) in rl_start_locked() to rl_encap() and
corrected memory synchronization operation specifier of
bus_dmamap_sync(9).
- Removed bus_dmamap_unload(9) in rl_stop(). There is no need to
reload/unload Rx buffer as rl(4) always have to copy from the
buffer. It just needs proper bus_dmamap_sync(9) calls before
copying the received frame.

Erase operation gives card's logic information about unused areas to help it
implement wear-leveling with lower overhead comparing to usual writing.
Erase is much faster then write and does not depends on data bus speed.
Also as result of hitting in-card write logic optimizations I have measured
up to 50% performance boost on writing undersized blocks into preerased areas.
At the same time there are strict limitations on size and allignment of erase
operations. We can erase only blocks aligned to the erase sector size and
with size multiple of it. Different cards has different erase sector size
which usually varies from 64KB to 4MB. SD cards actually allow to erase
smaller blocks, but it is much more expensive as it is implemented via

Only netbooting is supported at the moment.

FreeBSD 8-CURRENT was tested and run successfully on the following eval
boards and devices :
* DB-88F5182, DB-88F5281 (Orion based)
* DB-88F6281, RD-88F6281 (Kirkwood based)
* DB-78100 (Discovery based)

This supports 1Gbps Ethernet engine found on ARM-based SOCs (Orion, Kirkwood,
Discovery), as well as on system controllers for PowerPC processors (MV64430,
MV6446x).
The following advanced features are supported:
- multicast
- VLAN tagging
- IP/TCP/UDP checksum calculation offloading
- polling
- interrupt coalescing

the last byte of the ethernet address was not read which in turn
resulted in getting 5 out of the 6 bytes of ethernet address and
always returned ENOENT. I did not notice the bug on FPGA version
because of additional configuration data in EEPROM.

example the Huawei Mobile has an SD card slot on the second interface.
- Do not attach to Qualcomm and Novatel cards. If ignored these cards will
switch to modem mode automatically it seems.
- Reduce the priority on generic attachment to the appropriate level.
Note: A better solution is to send an eject command straightaway, but that can
be left till later.

The above families of SOCs are built around CPU cores compliant with ARMv5TE
instruction set architecture definition. They share a number of integrated
peripherals. This commit brings support for the following basic elements:
* GPIO
* Interrupt controller
* L1, L2 cache
* Timers, watchdog, RTC
* TWSI (I2C)
* UART
Other peripherals drivers will be introduced separately.

The physical page which we clear is accessed via additional temp kernel
mapping for the period of zeroing operation. However in systems with virtual
d-cache (most ARMs) when write-allocate feature is enabled, we can have
modified but unflushed content pertaining to this physical page still in the
d-cache due to its primary (pre-existing) mapping. In such scenario that
cached content upon flush is likely to overwrite [portions of] the physical
page we want to zero here..
This is a general problem with multiple virtual mappings covering the same
physical page with write-allocate and virtual d-cache: there is inherent
potential for corruptions of this kind, which are not easily resolved; it is
best policy that such multiple mappings be not allowed.

will ease the identification of memory leaks as the OS will be able to track
allocations for us by malloc type. vmstat -m will show all of the
allocations.
Convert the calls to drm_alloc() and friends, which are used in shared code
to static __inline__ while we are here.

Diff minimization against ldscript.mips.
Note: CFE will not load PT_DYNAMIC segments, therefore the dynamic
sections have been placed in a PT_LOAD segment for now. This is not
too efficient in terms of memory use, they should probably get
placed in the text segment.

is JMC260 Rev A0. This will make it easy for newer JMC2xx support.
