env: Rename getenv/_f() to env_get()

2017-08-16T12:30:24+00:00

We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.

Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.

env: Add an enum for environment state

2017-08-15T12:18:51+00:00

At present we have three states for the environment, numbered 0, 1 and 2.
Add an enum to record this to avoid open-coded values.

spl: make SPL and normal u-boot stage use independent SYS_MALLOC_F_LEN

2017-07-27T12:59:03+00:00

Some platforms have very limited SRAM to run SPL code, so there may
not be the same amount space for a malloc pool before relocation in
the SPL stage as the normal U-Boot stage.

Make SPL and (the full) U-Boot stage use independent SYS_MALLOC_F_LEN,
so the size of pre-relocation malloc pool can be configured memory
space independently.

bootstage: Support relocating boostage data

2017-06-05T18:13:06+00:00

Some boards cannot access pre-relocation data after relocation. Reserve
space for this and copy it during preparation for relocation.

bootstage: Convert to use malloc()

2017-06-05T18:13:04+00:00

At present bootstage uses the data section of the image to store its
information. There are a few problems with this:

- It does not work on all boards (e.g. those which run from flash before
relocation)
- Allocated strings still point back to the pre-relocation data after
relocation

Now that U-Boot has a pre-relocation malloc() we can use this instead,
with a pointer to the data in global_data. Update bootstage to do this and
set up an init routine to allocate the memory.

Now that we have a real init function, we can drop the fake 'reset' record
and add a normal one instead.

Note that part of the problem with allocated strings remains. They are
reallocated but this will only work where pre-relocation memory is
accessible after relocation.

asm-generic: global_data: change timebase_l/h to unsigned int

2017-05-12T12:37:35+00:00

Change type of timebase_l/h to unsigned int.
>From lib/time.c: ((uint64_t)gd->timebase_h << 32) | gd->timebase_l;
This piece code is based on that timebase_h and timebase_l are
32bits width, so change the type to unsigned int.

board_f: Drop board_type parameter from initdram()

2017-04-05T17:58:44+00:00

It looks like only cm5200 and tqm8xx use this feature, so we don't really
need it in generic code. Drop it and have the users access gd->board_type
directly.

spl: Add spl_early_init()

2017-03-16T22:03:43+00:00

At present malloc_base/_limit/_ptr are not initialised in spl_init() when
we call spl_init() in board_init_f(). This is due to a recent change aimed
at avoiding overwriting the malloc area set up on some boards by
spl_relocate_stack_gd().

However if CONFIG_SPL_STACK_R_MALLOC_SIMPLE_LEN is not defined, we now
skip setting up the memory area in spl_init() which is obviously wrong.

To fix this, add a new function spl_early_init() which can be called in
board_init_f().
