v2 cover configs: defconfigs for Atmel boards

Hi,

This series updates and adds defconfigs for the recent(ish) atmel boards. They use Atmel's u-boot and kernel tree and are meant to be flashed on the NAND flash.

It also provides a flahing helper to ease the flashing of the board and includes documentation on how to do so.

Changes in v2:
- Add flashing helper and instructions
- Update the existing xplained readme
- Use commit ids instead of branch names
- Include ubi image generation in the defconfig

Alexandre Belloni (9):
configs: update at91sam9g45m10ek defconfig
configs: add defconfig for Atmel at91sam9rlek
configs: add defconfig for Atmel at91sam9x5ek
configs: add defconfig for Atmel sama5d3xek
configs: add defconfig for Atmel sama5d4ek
configs: add defconfig for Atmel sama5d4 Xplained Ultra
configs: add defconfig for Atmel sama5d3 Xplained
atmel: add a flashing helper and documentation
configs: rename atmel_xplained_defconfig

You also need to ensure that the kernel headers used for the toolchain are of the same version or older than the kernel you're building/running.

So, something like:

BR2_KERNEL_HEADERS_VERSION=y
BR2_DEFAULT_KERNEL_VERSION="3.18"
BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_3_18=y

And ditto for all your other defconfigs.

Thanks!

PATCH v2 4/9 configs: add defconfig for Atmel sama5d3xek

Dear Alexandre Belloni,

Quoted 1 line · Alexandre Belloni

Hum, at some point we'll have to think about using $(wildcard ...) or something like that to allow wildcards in this option. But since there's only one user for now, and it's not very common to have gazillions of DTs for a given board, it's probably not worth the effort.

PATCH v2 8/9 atmel: add a flashing helper and documentation

Hi Alexandre,

board/atmel/nandflash.txt line 103

+You can then flash the board using the provided flasher.sh script in board/atmel:
+
+board/atmel/flasher.sh <builddir_path> <interface> <board>
+
+For example:
+board/atmel/flasher.sh /tmp/atmel_sama5d3_xplained/ /dev/ttyACM0 sama5d3_xplained

Since you didn't mention out of tree build in this document, I think './output/' would be better as first argument example. Adding a comment on out of tree build would be nice, though.

Yeah, I thought about that and that is why I used ./output in usage().

I'll switch to:

"
For example, for an out of tree build made in /tmp/atmel_sama5d3_xplained/ for the sama5d3 Xplained, you would use:
board/atmel/flasher.sh /tmp/atmel_sama5d3_xplained/ /dev/ttyACM0 sama5d3_xplained "

PATCH v2 8/9 atmel: add a flashing helper and documentation

In reply to Alexandre Belloni

Dear Alexandre Belloni,

Quoted 9 lines · Alexandre Belloni

Provide a flashing helper to properly select the sam-ba configuration and reuse the sam-ba tcl script provided by Atmel with minimal modifications.

This file should really be called readme.txt and not nandflash.txt. I know it doesn't cover anything but NAND flash for the moment, but readme.txt is really the convention we use for all platforms.

Otherwise, great job. I really like the tutorial covering all the evaluation boards, with details on connecting the debug UART and the USB device cable.

Thanks!

Thomas

PATCH v2 9/9 configs: rename atmel_xplained_defconfig

In reply to Alexandre Belloni

For consistency, rename atmel_xplained_defconfig to atmel_sama5d3_xplained_mmc_defconfig as this configuration supports booting the sama5d3 Xplained with an MMC card (as opposed to the NAND flash).
