firmware: google: Properly state IOMEM dependency
The Google Coreboot implementation requires IOMEM functions (memmremap, memunmap, devm_memremap), but does not specify this is its Kconfig. This results in build errors when HAS_IOMEM is not set, such as on some UML configurations: /usr/bin/ld: drivers/firmware/google/coreboot_table.o: in function `coreboot_table_probe': coreboot_table.c:(.text+0x311): undefined reference to `memremap' /usr/bin/ld: coreboot_table.c:(.text+0x34e): undefined reference to `memunmap' /usr/bin/ld: drivers/firmware/google/memconsole-coreboot.o: in function `memconsole_probe': memconsole-coreboot.c:(.text+0x12d): undefined reference to `memremap' /usr/bin/ld: memconsole-coreboot.c:(.text+0x17e): undefined reference to `devm_memremap' /usr/bin/ld: memconsole-coreboot.c:(.text+0x191): undefined reference to `memunmap' /usr/bin/ld: drivers/firmware/google/vpd.o: in function `vpd_section_destroy.isra.0': vpd.c:(.text+0x300): undefined reference to `memunmap' /usr/bin/ld: drivers/firmware/google/vpd.o: in function `vpd_section_init': vpd.c:(.text+0x382): undefined reference to `memremap' /usr/bin/ld: vpd.c:(.text+0x459): undefined reference to `memunmap' /usr/bin/ld: drivers/firmware/google/vpd.o: in function `vpd_probe': vpd.c:(.text+0x59d): undefined reference to `memremap' /usr/bin/ld: vpd.c:(.text+0x5d3): undefined reference to `memunmap' collect2: error: ld returned 1 exit status Fixes: a28aad66da8b ("firmware: coreboot: Collapse platform drivers into bus core") Acked-By: anton ivanov <anton.ivanov@cambridgegreys.com> Acked-By: Julius Werner <jwerner@chromium.org> Signed-off-by: David Gow <davidgow@google.com> Link: https://lore.kernel.org/r/20220225041502.1901806-1-davidgow@google.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

This option enables the coreboot_table module, which provides other
firmware modules access to the coreboot table. The coreboot table
