You have integrated this NAND driver into the tqm8272.c source file. I suggest you move this at some time into the drivers/mtd/nand directory. Is it a

Why? That are just the boardspecific routines, not a complete NAND driver!

TQM8272 specific driver? Or is this MPC8xxx specific? From the name of the functions (upm_xxx) this seems to match the already available driver under:

drivers/mtd/nand/fsl_upm.c

Is it possible that you can use this common FSL-UPM version?

Maybe this is posible, but without the Hardware to try this new version, I dont like to make such a "big" change ...

Hello,

[POWERPC] TQM8272: Fix compiling error for the TQM8272 board.

tqm8272.c: In function 'upmnand_hwcontrol': tqm8272.c:1086: warning: implicit declaration of function 'writeb' tqm8272.c: In function 'board_nand_init': tqm8272.c:1193: error: 'struct nand_chip' has no member named 'write_byte' make[1]: *** [tqm8272.o] Error 1 make[1]: *** Waiting for unfinished jobs.... make: *** [board/tqc/tqm8272/libtqm8272.a] Error 2

introduced from commit:

Update MTD to that of Linux 2.6.22.1

author William Juul william.juul@datarespons.no Wed, 31 Oct 2007 12:53:06 +0000 (13:53 +0100) committer Scott Wood scottwood@freescale.com Tue, 12 Aug 2008 16:31:15 +0000 (11:31 -0500) commit cfa460adfdefcc30d104e1a9ee44994ee349bb7b

Also moved the NAND Code in a seperate File.

Couldnt try this patch, because I have no longer the Hardware :-(

Update since last Patch:

- move NAND functions from tqm8272.c in seperate nand.c File
