Subject: [PATCH] nvmem: rmem: select CONFIG_CRC32
Date: Mon, 28 Apr 2025 17:08:26 +0200 [thread overview]
Message-ID: <20250428150831.4001255-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
The newly added crc checking leads to a link failure if CRC32
itself is disabled:
x86_64-linux-ld: vmlinux.o: in function `rmem_eyeq5_checksum':
rmem.c:(.text+0x52341b): undefined reference to `crc32_le_arch'
Fixes: 7e606c311f70 ("nvmem: rmem: add CRC validation for Mobileye EyeQ5 NVMEM")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>

This driver maps reserved memory into an nvmem device. It might be
useful to expose information left by firmware in memory.
