[PATCH v4 00/13] x86: cbfs: Various clean-ups to CBFS implementation

[PATCH v4 00/13] x86: cbfs: Various clean-ups to CBFS implementation

[Simon Glass]

This code is very old and has not had much of a clean-up since it was
written. This series aims to tidy it up to use error codes, avoid using
BSS when not necessary and to add a few more features.

Changes in v4:
- Stick with US spelling
- Fix 'his' typo

Changes in v3:
- Fix typo in commit message

Changes in v2:
- Fix incorrect function comments
- Fix s/u8/void/ in find_uncached()
- Fix setting of start in file_cbfs_find_uncached()
- Add more comments on @node in file_cbfs_find_uncached()
- Use void * instead of u8 * in file_cbfs_find_uncached_base()
- Fix and expand comments in file_cbfs_find_uncached_base()
- Rebase to master (with x86/master cherry-picked in too)
- Resending as some comments / reviews were missed

Simon Glass (13):
  cbfs: Rename the result variable
  cbfs: Use ulong consistently
  cbfs: Use bool type for whether initialised
  cbfs: Adjust return value of file_cbfs_next_file()
  cbfs: Adjust file_cbfs_load_header() to use cbfs_priv
  cbfs: Adjust cbfs_load_header_ptr() to use cbfs_priv
  cbfs: Unify the two header loaders
  cbfs: Use void * for the position pointers
  cbfs: Record the start address in cbfs_priv
  cbfs: Return the error code from file_cbfs_init()
  cbfs: Change file_cbfs_find_uncached() to return an error
  cbfs: Allow reading a file from a CBFS given its base addr
  cbfs: Don't require the CBFS size with cbfs_init_mem()

[PATCH v4 01/13] cbfs: Rename the result variable

[Simon Glass]

At present the result variable in the cbfs_priv is called 'result' as is
the local variable in a few functions. Change the latter to 'ret' which is
more common in U-Boot and avoids confusion.

[PATCH v4 02/13] cbfs: Use ulong consistently

[Simon Glass]

U-Boot uses ulong for addresses but there are a few places in this driver
that don't use it. Convert this driver over to follow this convention
fully.

[PATCH v4 04/13] cbfs: Adjust return value of file_cbfs_next_file()

[Simon Glass]

At present this uses a true return to indicate it found a file. Adjust it
to use 0 for this, so it is consistent with other functions.

Update its callers accordingly and add a check for malloc() failure in
file_cbfs_fill_cache().

[PATCH v4 05/13] cbfs: Adjust file_cbfs_load_header() to use cbfs_priv

[Simon Glass]

This function is strange at the moment in that it takes a header pointer
but then accesses the cbfs_s global. Currently clients have their own priv
pointer, so update the function to take that as a parameter instead.

[PATCH v4 07/13] cbfs: Unify the two header loaders

[Simon Glass]

These two functions have mostly the same code. Pull this out into a common
function.

Also make this function zero the private data so that callers don't have
to do it. Finally, update cbfs_load_header_ptr() to take the base of the
ROM as its parameter, which makes more sense than passing the address of
the header within the ROM.

[PATCH v4 08/13] cbfs: Use void * for the position pointers

[Simon Glass]

It doesn't make sense to use u8 * as the pointer type for accessing the
CBFS since we do not access it as bytes, but via structures. Change it to
void *, which allows us to avoid a cast.

[PATCH v4 09/13] cbfs: Record the start address in cbfs_priv

[Simon Glass]

The start address of the CBFS is used when scanning for files. It makes
sense to put this in our cbfs_priv struct and calculate it when we read
the header.

Update the code accordingly.

but leave it for now.

[PATCH v4 11/13] cbfs: Change file_cbfs_find_uncached() to return an error

[Simon Glass]

This function currently returns a node pointer so there is no way to know
the error code. Also it uses data in BSS which seems unnecessary since the
caller might prefer to use a local variable.

Update the function and split its body out into a separate function so we
can use it later.

It looks there are build errors for sandbox/x86:
https://dev.azure.com/bmeng/GitHub/_build/results?buildId=229&view=logs&j=8a1d3be7-a4c9-55b6-774d-e7f1a8f80847&t=b2f224a7-1103-5b52-edbc-3784ae727e03

Could you please take a look?
