From 60013790aa6b8ba65fdb7546f715314d00591f81 Mon Sep 17 00:00:00 2001
From: Tejas Bhumkar <tejas.arvind.bhumkar@amd.com>
Date: Fri, 7 Jun 2024 06:32:58 -0400
Subject: [PATCH] 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.
