Subject: [PATCH v2 00/11] Generic powerpc fixes and NXP board cleanup
Date: Wed, 6 May 2026 14:34:09 +0200 [thread overview]
Message-ID: <20260506123507.2081751-1-mwalle@kernel.org> (raw)
While working on an ancient P2041 based board, I've encountered
several issues.
cpu_init_r wasn't called anymore, but u-boot was still somehow
working. CAAM was reading/writing on address 0 because pamu_init()
is never called if secure boot isn't enabled.
Since legacy ethernet was removed, board_eth_init() and
fdt_fixup_board_enet() won't be called anymore, but the functions
are still defined. I've just removed the ones for the NXP boards,
though I think the code there did something useful. But given that
it wasn't called for two years now and nobody complained, it can't
be that important.
Lastly, because I have a p2041rdb, move that to a upstream DTS.
Keep in mind, that the uboot dts doesn't define an UART, so any
output was broken since the move to DM provided serial support.
v2:
- new patch
p2041rdb: convert README to rst
- fix build errors, tested all commits with buildman
Michael Walle (11):
powerpc: fix call to cpu_init_r
caam: don't write memory at 0 on PPC
spi: fsl_espi: fix read transactions
boards: remove dead fman code
boards/nxp: remove board_eth_init()
boards/nxp: remove empty fdt_fixup_board_enet()
p2041rdb: use the upstream device tree
p2041rdb: support SDcard boot
p2041rdb: update README and fix typos
p2041rdb: remove NAND defconfig
p2041rdb: convert README to rst
