lmb: replace the lmb_alloc() and lmb_alloc_base() API's

2025-06-25T15:50:37+00:00

There currently are two API's for requesting memory from the LMB
module, lmb_alloc() and lmb_alloc_base(). The function which does the
actual allocation is the same. Use the earlier introduced API
lmb_alloc_mem() for both types of allocation requests.

lmb: replace lmb_reserve() and lmb_alloc_addr() API's

2025-06-25T15:50:37+00:00

There currently are multiple allocation API's in the LMB module. There
are a couple of API's for allocating memory(lmb_alloc() and
lmb_alloc_base()), and then there are two for requesting a reservation
for a particular memory region (lmb_reserve() and
lmb_alloc_addr()). Introduce a single API lmb_alloc_mem() which will
cater to all types of allocation requests and replace lmb_reserve()
and lmb_alloc_addr() with the new API.

Moreover, the lmb_reserve() API is pretty similar to the
lmb_alloc_addr() API, with the one difference being that the
lmb_reserve() API allows for reserving any address passed to it --
the address need not be part of the LMB memory map. The
lmb_alloc_addr() does check that the address being requested is
actually part of the LMB memory map.

There is no need to support reserving memory regions which are outside
the LMB memory map. Remove the lmb_reserve() API functionality and use
the functionality provided by lmb_alloc_addr() instead. The
lmb_alloc_addr() will check if the requested address is part of the
LMB memory map and return an error if not.

bootm: Fix bmi->images pointer not initialized in some cases

2025-05-30T19:43:37+00:00

When building with only bootz command, without bootm, images pointer
inside bootm_info structure is not initialized. And since this structure
is stored in stack, the generated error is kind of random, but most of
the time this will generate: "ramdisk - allocation error".

Also, after analysis, this problem could occur with the command booti,
if the command bootm is disabled.

Currently bootm_init() is called by: do_bootz(), do_bootm(), do_booti()
and by do_stm32prog(). And all of these commands execute bootm_run_states()
which access the images pointer stored into bootm_info structure.

So, to fix this issue, just do the assignment unconditionally.

bootm: improve error message when gzip decompression buffer is too small

2025-05-05T20:16:57+00:00

Currently, when decompressing a gzip-compressed image during bootm, a
generic error such as "inflate() returned -5" is shown when the buffer is
too small. However, it is not immediately clear that this is caused by
CONFIG_SYS_BOOTM_LEN being too small.

This patch improves error handling by:
- Detecting Z_BUF_ERROR (-5) returned from the inflate() call
- Suggesting the user to increase CONFIG_SYS_BOOTM_LEN when applicable
- Preserving the original return code from zunzip() instead of overwriting
  it with -1

By providing clearer hints when decompression fails due to insufficient
buffer size, this change helps users diagnose and fix boot failures more
easily.

lmb: Remove lmb_reserve_flags()

2024-12-30T19:21:55+00:00

lmb_reserve() is just calling lmb_reserve_flags() with LMB_NONE.
There's not much we gain from this abstraction.
So let's remove the latter, add the flags argument to lmb_reserve()
and make the code a bit easier to follow.

All three addresses printed are in hexadecimal format, but only the
first two have the "0x" prefix. The patch aligns the format of the
"end" address with the other two by adding the "0x" prefix.

With the move to make the LMB allocations persistent and the common
memory regions being reserved during board init, there is no need for
an explicit reservation of a memory range. Remove the
lmb_init_and_reserve_range() function.

lmb: allow lmb module to be used in SPL

2024-09-03T20:08:50+00:00

With the introduction of separate config symbols for the SPL phase of
U-Boot, the condition checks need to be tweaked so that platforms that
enable the LMB module in SPL are also able to call the LMB API's. Use
the appropriate condition checks to achieve this.
