a71c657475 Make vers.c creation atomic by using a temporary file, then moving
the temporary file to vers.c at the end of the script

The previous logic wrote out to vers.c multiple times, so the file
could be incorrectly interpreted as being completely written out
after one of the echo calls with recursive make, when in reality it
was only partially written.

Also, in the event the build was interrupted when creating vers.c
(small race window), it would have a leftover file that needed to
be cleaned up before resuming the build.

889592b876 Change gptldr from relocating 0xfff1 bytes of boot2 to relocating 0x20000
bytes of boot2.  Since we're in 16-bit mode, we can't copy all 128kB at
once; instead we loop four times and copy 32 kB each time.

This change was made necessary by an upcoming increase in the size of the
boot2 binary; should it increase further, the COPY_BLKS value can be
adjusted without anyone needing to remember 8086 assembly language again.

b2e38974e2 The EFI boot loader allocates a single chunk of contiguous memory to
hold the kernel, modules, and any other loaded data.  This memory block
is relocated to the kernel's expected location during the transfer of
control from the loader to the kernel.

The GENERIC kernel on amd64 has recently grown such that a kernel + zfs.ko
no longer fits in the default staging size.  Bump the default size from
32MB to 48MB to provide more breathing room.

40ea8e710e As expected, things aren't as simple as hoped. Consequently, we have
no option but to use the smbios information to fill in the blanks.
It's a good thing UGA is a protocol of the past and GOP has all the
info we need.

Anyway, the logic has been tweaked a little to get the easier bits
of information up front. This includes the resolution and the frame
buffer address. Then we look at the smbios information and define
expected values as well as the missing bits (frame buffer offset and
stride). If the values obtained match the expect values, we fill in
the blanks and return. Otherwise we use the existing detection logic
to figure it out.

Rename the environment variables from uga_framebuffer abd uga_stride
to hw.efifb.address and hw.efifb.stride. The latter names are more
in line with other variable names.

We currently have hardcoded settings for:
1.  Mid-2007 iMac (iMac7,1)
2.  Late-2007 MacBook (MacBook3,1)

1f8577e633 Auto-detect the UGA frame buffer and stride on a MacBook. We're
striking a delicate balance between exhaustive searching and
banking on assumptions. The environment variables can be used
as a fall-back anyway. With this change, all known and tested
Macs with only UGA should have a working console out of the
box... for now...

39993974aa My MacBook has UGA only, but we fail to detect any changes
in the frame buffer when we flip pixels. Allow the detection
to be bypassed by setting the uga_framebuffer and uga_stride
variables. The kernel console works fine even when we can't
detect pixel changes in the frame buffer, which indicates
that the problem could be with reading from the frame buffer
and not writing to it.

Marcel Moolenaar
504ca52575 For UGA, the frame buffer address obtained by scanning the
PCI BARs does not necessarily correspond to the upper-left
most pixel. Scan the frame buffer for which byte changed
when changing the pixel at (0,0).

Use the same technique to determine the stride. Except for
changing the pixel at (0,0), we change the pixel at (0,1).

7aefa262d6 Add support for the UGA draw protocol. This includes adding a
command called 'uga' to show whether UGA is implemented by the
firmware and what the settings are. It also includes filling
the efi_fb structure from the UGA information when GOP isn't
implemented by the firmware.

Since UGA does not provide information about the stride, we
set the stride to the horizontal resolution. This is likely
not correct and we should determine the stride by trial and
error. For now, this should show something on the console
rather than nothing.

Refactor this file to maximize code reuse.

43ea03d756 Improve the realtime properties of USB transfers for embedded systems
like RPI-B and RPI-2.

Description of problem:
USB transfers can process data in their callbacks sometimes causing
unacceptable latency for other USB transfers. Separate BULK completion
callbacks from CONTROL, INTERRUPT and ISOCHRONOUS callbacks, and give
BULK completion callbacks lesser execution priority than the
others. This way USB audio won't be interfered by heavy USB ethernet
usage for example.

Further serve USB transfer completion in a round robin fashion,
instead of only serving the most CPU hungry. This has been done by
adding a third flag to USB transfer queue structure which keeps track
of looping callbacks. The "command" callback function then decides
what to do when looping.

7ec8c789c3 Add AHCI attachment code for Allwinner A10/A20 SoCs.
The Allwinner SoC has an AHCI device on its internal main bus rather
than the PCI bus.  This SoC is somewhat underdocumented, and its SATA
controller is no exception.  The methods to support this chip were
harvested from the Linux Allwinner SDK, and then constants invented to
describe what's going on based on low-level constants contained in the
SATA standard and guess work.

This SoC requires a specific AHCI channel setup in order to start the
operations on the channel properly.

Clock setup and AHCI channel setup idea came from NetBSD.

Tested on Cubieboard 2 and Banana pi (and attachment on Cubieboard by
Pratik Singhal).

15e862e33c Provide bug4bug workaround for certain dumbiness of the u-boot's API_env_enum
function, which is expected to set returned env to NULL upon reaching the end
of the environment list but fails to do so in certain cases. The respective
u-boot code looks like the following (HEAD at the time of this commit):

--- api.c ---
 496 static int API_env_enum(va_list ap)
 ...
 510                 *next = last;
 511
 512                 for (i = 0; env_get_char(i) != '\0'; i = n + 1) {
 513                         for (n = i; env_get_char(n) != '\0'; ++n) {
 514                                 if (n >= CONFIG_ENV_SIZE) {
 515                                         /* XXX shouldn't we set *next = NULL?? */
 516                                         return 0;
 517                                 }
 518                         }
-------------

The net result is that any unfortunate user of the loader's ub_env_enum()
function hitting this condition would be trapped in the infinite loop, as
the main use pattern of ub_env_enum() is basically the following:

while ((env = ub_env_enum(env)) != NULL) { DO STUFF }

Which would stuck forever with the last element.

8f207db125 Fix bug in the ubldr introduced in the rev.283035. The new code
fails to properly consider memory regions when the loader is
located below of those regions or engulfs their lower limit. This
results in "not enough RAM to load kernel" panic, which is totally
bogus. On top of that, there are some variables that can be left
unitialized in those cases, which might cause it fail with memory
access violation instead of panic while trying to load kernel to
a wrong or non-existing address of memory.

Augment the code to properly deal with the loader being below or
at the lower bound of the memory region in question. Also, don't
leave ununitialized variables behind.
