-Subject: [PATCH RFC] bcma: use two different initcalls if built-in
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This is needed as we can't initialize bus during fs_initcall.
-Initialization requires SPROM which depends on NVRAM which depends on
-mtd. Since mtd, spi, nand, spi-nor use standard module_init, we have to
-do the same in bcma.
-Without this we'll try to initialize SPROM without having a ready SPROM
-proviver registered using bcma_arch_register_fallback_sprom.
-
-Signed-off-by: Rafał Miłecki <zajec5@gmail.com>
----
-While this patch seems to work and I can compile bcma as built-in and
-module, I'm not too proud of it. I don't really like these #if(n)def
-tricks and I'm afraid bcma_modinit may be called even if
-bcma_modinit_early failed.
-
-Do you see any better idea of solving this?
