Alpha MTD_TSUNAMI BROKEN?

Hi,

In an alpha kernel config with CONFIG_ALPHA_TSUNAMI=y
and CONFIG_MTD_TSUNAMI=y, the MTD driver build fails with:

../drivers/mtd/maps/tsunami_flash.c: In function 'tsunami_flash_read8':
../drivers/mtd/maps/tsunami_flash.c:21:20: error: implicit declaration of function 'tsunami_tig_readb'; did you mean 'tsunami_readb'? [-Werror=implicit-function-declaration]
21 | val.x[0] = tsunami_tig_readb(offset);
| ^~~~~~~~~~~~~~~~~
| tsunami_readb
../drivers/mtd/maps/tsunami_flash.c: In function 'tsunami_flash_write8':
../drivers/mtd/maps/tsunami_flash.c:27:9: error: implicit declaration of function 'tsunami_tig_writeb'; did you mean 'tsunami_writeb'? [-Werror=implicit-function-declaration]
27 | tsunami_tig_writeb(value.x[0], offset);
| ^~~~~~~~~~~~~~~~~~
| tsunami_writeb


The tsunami_tig_{readb,writeb{}() functions are completely missing.
I don't see any macros that would generate such function names.

I have searched both kernel/git/history/history.git and
kernel/git/mpe/linux-fullhistory.git (both at git.kernel.org)
and found no such functions. (It's possible that I could have
missed something here: all I did was 'git grep tsunami_tig'.
Do I need to do 'git checkout <something really old>' first?)

Should these functions just be tsunami_readb() and tsunami_writeb()
like the compiler asks?
Or should we mark this driver as BROKEN?

Thanks.
