Since Buildroot commit [1] "package/gcc: switch to GCC 15.x as the
default", compiling freescale_imx93frdm_defconfig fails in TF-A with
error:
include/drivers/nxp/trdc/imx_trdc.h:7: error: header guard 'IMX_TRDC_H' followed by '#define' of a different macro [-Werror=header-guard]
7 | #ifndef IMX_TRDC_H
include/drivers/nxp/trdc/imx_trdc.h:8: note: 'IMX_XRDC_H' is defined here; did you mean 'IMX_TRDC_H'?
8 | #define IMX_XRDC_H
The issue happen because this defconfig is using a Buildroot
(internal) toolchain which uses gcc version 15 by default.
This issue was fixed upstream in [2], first included in TF-A v2.13.
This commit updates U-Boot, TF-A and Linux to use the NXP
tag lf-6.18.20-2.0.0, which include this fixes.
Note that, as described in the commit log of [3] which introduced
this defconfig, U-Boot and Linux were forks. Now the necessary
patches are included in the vendor BSP, this commit switches those
repos to use the vendor ones.
While at it, this commit also switches the defconfig to use an
external glibc stable Bootlin toolchain, to follow recommendations
from [4]. Since an external toolchain is used, the linux-headers.hash
custom hash file is no longer needed and is also removed. At the
time of this commit, the Bootlin stable toolchain is a gcc 14.
Also, due to the upstream uboot commit [5], this commit adds a uboot
config fragment to disable CONFIG_EFI_CAPSULE_AUTHENTICATE, to
remove the dependency on the command "cert-to-efi-sig-list", provided
the host efitools package, which is not yet in Buildroot.
This commit was run tested on board 700-94611 Rev B1.

This commit adds support for the i.MX 93 FRDM (Freedom) board.
The i.MX93 FRDM development board is a low-cost and compact
development board featuring the i.MX93 applications processor.
See: https://nxp.com/FRDM-IMX93
This defconfig is based on freescale_imx93evk_defconfig introduced
by Sébastien, in Cc.
Note: the Linux and U-Boot repositories are forks. This is because
the NXP software team did not included all the necessary i.MX93 FRDM
patches in the standard NXP i.MX BSP at the time of this commit.
Instead, patches were published in a dedicated Yocto Layer from [1].
The forks used in this defconfig are simply the repositories [2]
and [3] with patches from [1] applied on them. This is only to make this
defconfig simpler in the meantime the BSP patches are included in the
NXP BSP repositories.
Thanks to Martin Chabot for lending a board!
