[U-Boot] [PATCH v2] arm : Atmel : add at91sam9x5ek board support
Add at91sam9x5ek board support, this board support the following SoCs AT91SAM9G15, AT91SAM9G25, AT91SAM9G35, AT91SAM9X25, AT91SAM9X35
Using at91sam9x5ek_nandflash to configure for the board Now only supports NAND with software ECC boot up
This patch is based on git://git.denx.de/u-boot-atmel.git

NAK, I count this worse than before. a) including relative path b) cidr == fidi && ner == fidi ??; how about exid? c) struct atmel_usart3_t has same footprint in view of USART, but using that struct in this use case is wrong. If you fear to add some specific struct atmel_dbgu to arch specific includes please revert to first version with comment about the magic numbers.

NAK, I count this worse than before. a) including relative path b) cidr == fidi && ner == fidi ??; how about exid? c) struct atmel_usart3_t has same footprint in view of USART, but using that struct in this use case is wrong. If you fear to add some specific struct atmel_dbgu to arch specific includes please revert to first version with comment about the magic numbers.
I will use the first version with comments.

Ouch, that slipped through in last review. This is copied from at91sam9g45_matrix.h.
If at91sam9x5 matches at91sam9g45 why another include? If not please change the source of information (and include guards some lines down).
I will correct this.

I will move it into at91sam9x5.h file.
can we use something like AT91_CIDR_VERSION_MASK or ATMEL_CIDR_VERSION_MASK? I guess this is in every DBGU integrated and could later be used to identify different atmel devices.

Well, it is ok with me to use read.jffs2 (if it works). I just do not know about that subcommand and I can only find some references about that in two other boards. I guess these boards are just forgotten while removing the 'nand read.jffs2' command. Please check, if that command works, if yes let it as is, if not rewrite.

I am in favor of using read.jffs2 because it is able to skip bad blocks. As the programming tool is also skipping bad blocks the same way, we have a configuration that is perfectly working even in case of bad block in the middle of the kernel image.
So please, keep using read.jffs2 (or equivalent)!

..." skipping bad blocks."...
So it seems that simple "nand read/write" is what we are looking for... in comparison with read.raw/write.raw. Fair enough: nand read/write is the way to go, now.

Ok, some investigation showed up that a) the default read/write should skip bad blocks since 984e03cdf1431bb593aeaa1b74c445d616f955d3 (mid of 2008!) b) the .jffs2 subcommand is still available, but not in the help -> in line 645: if (!s || !strcmp(s, ".jffs2") ||
Since the read.jffs2 seems to be a leftover from older days I tend to use just 'nand read' here. But as said before, I will also take the 'nand read.jffs2' if it works. My first objection was that I doubt it works at all.
