   4 Subject: [PATCH] mtd: add arch dependency for MTD_BCM47XXSFLASH symbol

   9 We dropped strict MIPS dependency for bcm47xxsflash driver in:
  10 commit 5651d6aaf489 ("mtd: bcm47xxsflash: use ioremap_cache() instead of
  11 KSEG0ADDR()") but using ioremap_cache still limits building it to few
  12 selected architectures only.
  13
  14 A recent commit 57d8f7dd2132 ("bcma: allow enabling serial flash support
  15 on non-MIPS SoCs") automatically dropped MIPS dependency for
  16 MTD_BCM47XXSFLASH which broke building e.g. on powerpc and cris.
  17
  18 The bcma change is alright as it doesn't break building bcma code in any
  19 way. MTD_BCM47XXSFLASH on the other hand should be limited to archs
  20 which need it and can build it (by providing ioremap_cache).
