[U-Boot] [PATCH v5 00/11] arm, davinci: add support for dm368 based cam_enc_4xx board

This is a repost of the cam_enc_4xx board support patches from http://lists.denx.de/pipermail/u-boot/2011-October/106692.html
changes for v5: - rebase against TOT ce5207e191c59b3135303fd03b98dd2ac3701ba2 - add comment from Christian Riesch: use lpsc_on() and lpsc_syncreset(), remove dm365_lpc_transition() patches http://patchwork.ozlabs.org/patch/114942/ http://patchwork.ozlabs.org/patch/119375/ needed for this.
Patches are checkpatch clean
"./MAKEALL -a arm --soc davinci" compiles clean with patch: http://patchwork.ozlabs.org/patch/122348/
Also needed patches:
[U-Boot] net, davinci_emac: fix compiler error http://patchwork.ozlabs.org/patch/122348/
arm, arm926: fix missing symbols in NAND_SPL mode http://patchwork.ozlabs.org/patch/104942/
arm, davinci: replace CONFIG_PRELOADER with CONFIG_SPL_BUILD http://patchwork.ozlabs.org/patch/106983/
[U-Boot,v2,2/3] arm, davinci: Add function lpsc_syncreset() http://patchwork.ozlabs.org/patch/119375/
Albert? Maybe this patchset has a chance to go now in mainline? It is pending now since Sat Jul 16 12:06:41 CEST 2011, see: http://lists.denx.de/pipermail/u-boot/2011-July/096302.html

I'd suggest, instead of closing the weak declaration inside ifdef/ifndef, make it available to all boards with alias.

OK, done.
Thanks for the review.

This is common to most NAND SPLs. It would be nice to stick this in a common place (at least the loading part, maybe not the jump). Not nand_spl_simple.c, as it's utility is not limited to the simple driver. Maybe drivers/mtd/nand/nand_spl_load.c?

This is common to most NAND SPLs. Â It would be nice to stick this in a common place (at least the loading part, maybe not the jump). Â Not nand_spl_simple.c, as it's utility is not limited to the simple driver. Â Maybe drivers/mtd/nand/nand_spl_load.c?
Indeed, the difference right here between davinci and omap*(/am335x) is parsing u-boot.img for the size or just using a hard-coded size variable.

moved to drivers/mtd/nand/spl_nand_load.c, also I want to let the jump in this file. I prefer the name "spl_nand_load.c as we have already a
CONFIG_SPL_NAND_SIMPLE -> CONFIG_SPL_NAND_LOAD -> spl_nand_load.c
Is this OK for you?
Shouldn;t we rename nand_spl_simple.c to spl_nand_simple.c also?

I suggested nand_spl_load.c because we already have a nand_spl_simple.c. :-)
I don't really care which way it goes, as long as it's consistent.

similiar to commit dc7cd8e59ba077f3b4c1a4557c9cd86a31b9ab1f, only adapted for the new spl framework.

Hi Heiko,
I already see a patch for printing cpu info for dm365(rather for all davinci family) . Link for the patchhttp://www.mail-archive.com/u-boot@lists.denx.de/msg65514.html, which is more cleaner.
Regards --Prabhakar Lad

--- changes for v2: - rebase to TOT - adapted to new spl framework - add USB support - MDIO Clk only 1MHz - LED: set LED in spl code, and clear them after 1 second - add "bdinfo" command - add nandrbl board specific command for switching between rbl and uboot ecc calculation algorithm
changes for v3: - add CONFIG_SYS_NAND_HW_ECC_OOBFIRST
changes for v4: - add comments from Igor Grinberg - remove in board/ait/cam_enc_4xx/Makefile unnecessary targets clean, distcelan - use CONFIG_MACH_TYPE option - removed some unnecessary brackets - new patch: add a weak enable_vbus() in drivers/usb/musb/davinci.c - add a comment to an "#else" to make it clearer to which "#if" it belongs
- fix ALL to ALL-y in board config.mk, and add this only if CONFIG_SPL_BUILD is not set.
