[U-Boot] [PATCH] nios2: add 10m50 devboard support
Add 10m50 devboard support. It is based on the Golden Hardware Reference Design (GHRD), available at,
http://rocketboards.org/foswiki/view/Documentation/ AlteraMAX1010M50RevCDevelopmentKitLinuxSetup
Though we supported only one nios2-generic board in the past. Now, with the removal of the nios2-generic board dir, adding new nios2 boards to u-boot is easier than before. It should be helpful to add those boards supported in Linux mainline. There are only two such nios2 boards, the 3c120 devboard and 10m50 devboard. The nios2-generic is actually 3c120, and should restore the name. The 10m50 is this one.

Indeed, this patch is an excellent example of adding a new nios2 board.
Just a few nitpicks below.

Add Altera Generic Quad SPI Controller support. The controller converts SPI NOR flash to parallel flash interface. So it is not like other SPI flash, but rather like CFI flash.

Add 10m50 devboard support. It is based on the Golden Hardware Reference Design (GHRD), available at,
http://rocketboards.org/foswiki/view/Documentation/ AlteraMAX1010M50RevCDevelopmentKitLinuxSetup
Though we supported only one nios2-generic board in the past. Now, with the removal of the nios2-generic board dir, adding new nios2 boards to u-boot is easier than before. It should be helpful to add those boards supported in Linux mainline. There are only two such nios2 boards, the 3c120 devboard and 10m50 devboard. The nios2-generic is actually 3c120, and should restore the name. The 10m50 is this one.
