Subject: [PATCH] mtd: add arch dependency for MTD_BCM47XXSFLASH symbol
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
We dropped strict MIPS dependency for bcm47xxsflash driver in:
commit 5651d6aaf489 ("mtd: bcm47xxsflash: use ioremap_cache() instead of
KSEG0ADDR()") but using ioremap_cache still limits building it to few
selected architectures only.
A recent commit 57d8f7dd2132 ("bcma: allow enabling serial flash support
on non-MIPS SoCs") automatically dropped MIPS dependency for
MTD_BCM47XXSFLASH which broke building e.g. on powerpc and cris.
The bcma change is alright as it doesn't break building bcma code in any
way. MTD_BCM47XXSFLASH on the other hand should be limited to archs
which need it and can build it (by providing ioremap_cache).
Fixes: 57d8f7dd2132 ("bcma: allow enabling serial flash support on non-MIPS SoCs")

BCMA bus can have various flash memories attached, they are
registered by bcma as platform devices. This enables driver for
