r264400:

NO_MAN= has been deprecated in favor of MAN= for some time, go ahead
and finish the job. ncurses is now the only Makefile in the tree that
uses it since it wasn't a simple mechanical change, and will be
addressed in a future commit.

r265836:

Remove last two NO_MAN= in the tree. In both of these cases, MAN= is
what is needed.

Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this
shifts into the sign bit. Instead use (1U << 31) which gets the
expected result.

Similar to the (1 << 31) case it is not defined to do (2 << 30).

This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.

A similar change was made in OpenBSD.

Hack to unbreak boot2 for at91rm9200 boot loader. When the at91sam
code came in, it moved things around which wound up breaking the
build. We have to do this bit of a hack to avoid duplication of a lot
of #defines.

Replace `inline static' by `static inline'.

If I interpret the C standard correctly, the storage specifier should be
placed before the inline keyword. While at it, replace __inline by
inline in the files affected.

BWCT boards can have 128MB SDRAM.

BWCT boards uses two different SPI flash chips

Fix signedness to make gcc happy.

Load the bytes into the EMAC's MAC address register in the proper
order. The kernel used to shuffle them around to get things right,
but that was recently fixed. This makes our boot loader match the
behavior of most other boot loaders for the atmel parts. This bug was
inherited from the Kwikbyte loader that we started from.

This bug was discovered by Bj?\027.A?\027Nvrn K?\027Nvnig back in June, but fell on the
floor. He provided patches to the kernel, include backwards
compatibility options that were similar to Olivier's if_ate.c commit.

Use the .S version for now. I have a version optimized for size p4,
but I'm unsure of its provenance, so rather than add it here, revert
the migration to it.

MFp4:
Add support for the CENTIPAD board (http://www.harerod.de/centipad/index.html)
(which is a very cool, very small ARM board)
Add support for KB9202B (it has different memory)
Make BOOT_FLAVOR settable
Minor cleanup nits

RTC_TIMR's RTC_SEC field is BCD. That makes it unsuitable for
GetSeconds(). Instead, use CRTR register shifted right 15. This
gives us a range of 32 seconds we can do for timeout.

Shift to using == rather than < or > for calculating the timeout,
since if we can't read the ST_CTRT register twice in a second we have
even bigger problems to worry about, and == deals with the 'wrap'
issue.

This lets me type at the boot2 prompt again! Woo Hoo!

Bogusness noticed by: tisco
Pointy Hat to: That silly imp guy

Since we're about to set ST_RTMR to 1 to increase the accuracy of the
CRTR register to be 1/32768th of a second in init, we don't need to do
it here.

All SD cards have a block size of 512. The READ_BL_LEN field in the
CSD is usually 512 (well, 9), but for 2GB (and the rogue 4GB SD cards)
it is 1024 (or 2048 for 4GB). This value doesn't work for the block
read commands (which really want 512). Hardcode 512 for those. This
may break really old MMC cards that don't have a 512 block size (I've
never seen one: make my day and send me one :-), but since the MMC
side of the house is currently broken, it should only have the effect
that 2GB (and non-conforming 4GB) SD cards will work.

My 'non-conforming' 4GB SD card also works now too. The
non-conforming 4GB SD cards were sold for a while before the SD
association was worried they would be (a) incompatible (different FAT
flavor on them) and (b) confusing for the new SDHC standard and
cracked down on suppliers' bogus use of the SD trademark...

Fix problem where memcmp would return true in the case where the

Remove vestiges of very specific fpga support for my company's board.
It isn't relevant to FreeBSD as a whole, breaks the build, and isn't
even needed for my company's boards anymore...

MFp4: differences for bwct ethernet attachment

MFp4: Differences in flash part for bwct. need a more generic way to cope.

MFp4: Add timeout to eeprom access for lame eeprom that go awol

MFp4: bwct memory size and PLL parameters

MFp4: bwct boot rom is different. need a more generic way to cope long term.

Mfp4: Remove mci_device.c. It should have been removed when it was
merged ito sd-card.c, but this is an imperfect world.

Move to using a common arm_init.S. These things are more similar than
different at this point.

MFp4: boot on KB9202 correctly. Also, reduce the size of the SD/MMC driver
somewhat.

There's no fpga.c, so omit it.

MFp4:

Massive update. The highlights:
o dramatically cut memory usage by writing better, less intertwingled
code.
o implement booting off mmc/sd cards (sd only tested one at the moment)
o start to split out board specific stuff for boot2.

MFp4: First cut at making spi and/or sd card booting work, needs work

MFp4: remove obsolete files

MFp4:
Remove obsolete files in list
Add spi flash reading routines

MFp4: Numerous changes from p4 to try to improve tftp downloading,
reduce code footprint, etc. While some problems still remain, the
reliability of tftp is much improved.

MFp4: consolidate #include files down to lib.h

MFp4: These will migrate to the boot specific directories because they
are too hard to share between the different boot loaders.

MFp4: Make it clearer that the address passed to the eeprom routines is
really an offset within the eeprom device, and not a IIC address.

MFp4: Catchup with migration of some defines.

MFp4: Tweaks for our board.

MFp4: Increase character timeout to 10. Make it a #define for easier
changes in the future. This helps with getting started and to
overcome the really sucky level of granuality this timeout has in
getc. A timeout of 1 means 'wait until top of next second' rather
than 'wait for at least a second'.

MFp4:
Make getc(0) polling (this has the happy side effect of saving
8 bytes in the generated code).

MFp4: Loop forever getting characters... A kludge for now.

MFp4: Integrate support for building tag support for linux booting.

MFp4:

On the KB9202 go ahead and enable the flash controller so the boot
loader can access the parallel flash.

MFp4:

Make this compile, assuming that you have linux installed in a
sensible place. tag_list is disabled by default, since we don't
distribute linux, but it is desirable to allow the boot loader to boot
Linux or FreeBSD (mostly for testing).

MFp4:
Minor diffs to reduce diffs to p4.

MFp4 (checkpoint of work in progress):

o Use a directory layout that is more akin to the i386 boot layout.
o Create a libat91 for library routines that are used by one or more
of the boot loaders.
o Create bootiic for booting from an iic part.
o Create bootspi for booting from an spi part.
o Optimize the size of many of these routines (especially emac.c). Except
for the emac.c optimizations, all these have been tested.
o eliminate the inc directory, libat91 superceeds it.
o Move linker.cfg up a layer to allow it to be shared.
