arm: move C runtime setup code in crt0.S

2013-01-08T21:14:50+00:00

Move all the C runtime setup code from every start.S
in arch/arm into arch/arm/lib/crt0.S. This covers
the code sequence from setting up the initial stack
to calling into board_init_r().

Also, rewrite the C runtime setup and make functions
board_init_*() and relocate_code() behave according to
normal C semantics (no jumping across the C stack any
more, etc).

Some SPL targets had to be touched because they use
start.S explicitly or for some reason; the relevant
maintainers and custodians are cc:ed.

env: Add environment variable flags

2012-12-13T18:46:56+00:00

Currently just validates variable types as decimal, hexidecimal,
boolean, ip address, and mac address.

If the entry is not found in the env ".flags", then look in the static
one. This allows the env to override the static definitions, but prevents
the need to have every definition in the environment distracting you.

env: Add support for callbacks to environment vars

!!!fix comment in callback

env: Hide '.' variables in env print by default

2012-12-13T18:46:55+00:00

When printing all variables with env print, don't print variables that
begin with '.'.  If env print is called with a '-a' switch, then
include variables that begin with '.' (just like the ls command).

Variables printed explicitly will be printed even without the -a.

env: Refactor apply into change_ok

2012-12-13T18:46:55+00:00

Move the read of the old value to inside the check function.  In some
cases it can be avoided all together and at the least the code is only
called from one place.

Also name the function and the callback to more clearly describe what
it does.

Pass the ENTRY instead of just the name for direct access to the whole
data structure.

Pass an enum to the callback that specifies the operation being approved.

env: Consolidate common code in hsearch_r()

2012-12-13T18:46:54+00:00

The same chunk of code was replicated in two places and the following
changes will make that chunk grow a bit, so combine into a static func.

env: Refactor do_apply to a flag

2012-12-13T18:46:54+00:00

Use a flag in hsearch_r for insert mode passed from import to allow the
behavior be different based on use.

Now that "do_check" is called for all imports, ensure console init is
complete before updating the console on relocation import

Make linux kernel string funcs available to tools

2012-12-13T18:46:07+00:00

isspace() and strim() are not in the typical user-mode string.h, so
put them in a separate compilation unit so that they can be built into
tools that need them independent of the other common string functions.

This allows code shared by u-boot and the linux user-mode tools to link.

vsprintf:fix: Change type returned by ustrtoul

2012-12-13T18:46:02+00:00

The ustrtoul shall convert string defined size (e.g. 1GiB) to unsigned
long type (as its name implies).

Up till now it had returned int, which might cause problems with large
numbers (GiB range), when interpreted as U2 signed numbers.
