Some old GNU assemblers, such as v2.14 (ELDK 3.1.1), v2.16 (ELDK 4.1.0),
warns illegal global symbol references by bal (and jal also) instruction.
This does not happen with the latest binutils v2.18.
Here's an example on gth2_config:
mips_4KC-gcc -D__ASSEMBLY__ -g -Os -D__KERNEL__ -DTEXT_BASE=0x90000000 -I/home/skuribay/devel/u-boot.git/include -fno-builtin -ffreestanding -nostdinc -isy
stem /opt/eldk311/usr/bin/../lib/gcc-lib/mips-linux/3.3.3/include -pipe -DCONFIG_MIPS -D__MIPS__ -G 0 -mabicalls -fpic -pipe -msoft-float -march=4kc -mtune=4k
c -EB -c -o cache.o cache.S
cache.S: Assembler messages:
cache.S:243: Warning: Pretending global symbol used as branch target is local.
cache.S:250: Warning: Pretending global symbol used as branch target is local.
In principle, gas might be sensitive to global symbol references in PIC
code because they should be processed through GOT (global offset table).
But if `bal' instruction is used, it results in PC-based offset jump.
This is the cause of this warning.
In practice, we know it doesn't matter whether PC-based reference or GOT-
based. As for this case, both will work before/after relocation. But let's
fix the code.
This patch explicitly sets up a target address, then jump there.
Here's an example of disassembled code with/without this patch.

If you enable environment in the flash, but disable the embedded
option, and you disable the saveenv command, then the #if nested
logic will trigger a compile failure:
env_flash.c: In function 'env_relocate_spec':
env_flash.c:399: error: 'flash_addr' undeclared (first use in this function)
The fix is to add CMD_SAVEENV ifdef protection like everywhere else.

The mmap() related code is full of inconsistent casts/constants when
it comes to error checking, and may break when building on some
systems (like ones that do not implicitly define the caddr_t type).
Let's just avoid the whole mess by writing the code nice and clean in
the first place.

The Vitesse VSC8601 RGMII PHY has internal delay for both Rx
and Tx clock lines. They are configured using 2 bits in extended
register 0x17.
Therefore CFG_VSC8601_SKEW_TX and CFG_VSC8601_SKEW_RX have
been introduced with valid values 0-3 giving 0.0, 1.4,1.7 and 2.0ns delay.

Current trick to pick up GNU assembler minor version uses a dot(.) as a
delimiter, and take the second field to obtain minor version number. But
as can be expected, this doesn't work with a version string which has
dots more than needs.
Here's an example:
$ mips-linux-gnu-as --version | grep 'GNU assembler'
GNU assembler (Sourcery G++ Lite 4.2-129) 2.18.50.20080215
$ mips-linux-gnu-as --version | grep 'GNU assembler' | cut -d. -f2
2-129) 2
$
This patch restricts the version format to 2.XX.XX... This will work
in most cases.
$ mips-linux-gnu-as --version | grep 'GNU assembler' | egrep -o '2\.[0-9\.]+'
2.18.50.20080215
$ mips-linux-gnu-as --version | grep 'GNU assembler' | egrep -o '2\.[0-9\.]+' | cut -d. -f2

Some 86xx chips use CCB as the base clock for the I2C, and others used CCB/2.
There is no pattern that can be used to determine which chips use which
frequency, so the only way to determine is to look up the actual SOC
designation and use the right value for that SOC.

This problem shows up with parallel builds only; it results in
somewhat cryptic error messages like
$ JOBS=-j6 MAKEALL netstar
Configuring for netstar board...
arm-linux-ld: cannot find -lgeneric
make[1]: *** [eeprom.srec] Error 1
A few boards (like netstar and voiceblue) need some libraries for
building; however, the board Makefile does not contain any such
dependencies which may cause problems with parallel builds. Adding
such dependencies is difficult as we would also have to provide build
rules, which already exist in the respective library Makefiles.
To solve this, we make sure that all libraries get built before the
board code.
