[PATCH v4 05/25] efi_loader: Show the resulting memory address from an alloc

Simon Glass sjg at chromium.org
Sun Dec 1 16:24:24 CET 2024


Update efi_allocate_pool_ext() to log the pointer returned from this
call, which can be helpful when debugging.

Signed-off-by: Simon Glass <sjg at chromium.org>

(no changes since v3)

Changes in v3:
- Show the returned address rather than the pointer

Changes in v2:
- Use EFI_PRINT() instead of log_debug()
