Re-extract the kernel patches as a series. Re-extract the u-boot patches as "git format-patch" command. Unified patch extraction makes it easier to work with patches.

Subject: [PATCH 4/4] efi_loader : Suppress error print message
|
|
|
|
Currently, on certain Xilinx platforms, an issue has been
|
|
identified, manifesting as follows:
|
|
|
|
Starting kernel ...
|
|
|
|
efi_free_pool: illegal free 0x0000000077830040
|
|
efi_free_pool: illegal free 0x000000007782d040
|
|
efi_free_pool: illegal free 0x000000007782c040
|
|
|
|
The issue arises when the ramdisk image is relocated, placing
|
|
it within the previously allocated EFI memory region( as EFI
|
|
is established quite early in U-Boot). Consequently, when
|
|
attempting to release memory in the EFI memory region during
|
|
the handover process to the kernel,we encounter memory violations.
|
|
|
|
Highlighting that EFI remains active primarily during the
|
|
booting of an EFI application, and the lmb persists while
|
|
configuring images for the boot process. Since we aren't
|
|
utilizing the EFI memory region during the boot process,
|
|
there is no adverse impact even in the event of a violation.
|
|
|
|
Currently, there is an ongoing discussion regarding the handling
|
|
strategies of three memory allocators: malloc, lmb, and EFI. This
|
|
discussion is documented in the email chain
|
|
titled "Proposal: U-Boot memory management."
|
|
|
|
Therefore, it is advisable to suppress the print message during
|
|
the boot process for now.
