[U-Boot] [PATCH v3] Add initial support for Wandboard dual lite and solo.
From: Fabio Estevam fabio.estevam@freescale.com
Add initial support for Wandboard.
Wandboard is a development board that has two variants: one version based on mx6 dual lite and another one based on mx6 solo.
For details on the features of Wandboard, please refer to: http://www.wandboard.org/
Signed-off-by: Fabio Estevam fabio.estevam@freescale.com --- Changes since v2: - Also added support to the mx6solo variant. - Rebased against u-boot-imx
Changes since v1: - Use get_ram_size - Remove ARP_TIMEOUT - Remove unneeded "1u" MAINTAINERS | 1 + arch/arm/include/asm/arch-mx6/mx6dl_pins.h | 3 + board/wandboard/Makefile | 29 ++++ board/wandboard/wandboard.c | 181 ++++++++++++++++++++++++ boards.cfg | 2 + include/configs/wandboard.h | 207 ++++++++++++++++++++++++++++ 6 files changed, 423 insertions(+) create mode 100644 board/wandboard/Makefile create mode 100644 board/wandboard/wandboard.c create mode 100644 include/configs/wandboard.h

No, the SoC used is a mx6 "dual lite", not "dual".
mx6 variants are: quad, dual, dual-lite, solo, solo-lite.

I agree but the board name is 'Wandboard Dual', see http://wandboard.org/index.php/details
So I'd use their name as users will end looking for it.

If you look at the second row it says the chip is dual-lite.
Dual and dual-lite are not pin-to-pin compatible.
I don't want to call a board in U-boot of 'dual' if it uses a 'dual-lite' processor.

I understand your point but we use board names not directly linked to the SoC they use, we name mx28evk and not mx287evk; mx23evk, not mx233evk ... but ok.

mx233 is still a mx23 processor. mx287 is still a mx28 processor.
mx6q / mx6dual / mx6dual-lite / mx6solo and mx6solo-lite are different processors.

But that would lead into unsolvable conflict if there should ever be a Wandboard with a dual (not a dual-lite) processor...
I agree with Fabio here.
