tegra: seaboard: disable SPI, move environment to eMMC 2012-07-07T12:07:21+00:00 Stephen Warren swarren@nvidia.com 2012-05-24T11:38:39+00:00 f9f2f12e2cace3685ea0dbb6b6d78789fb75f043 The SPI hardware on Seaboard is too broken to use; it is muxed with the console UART and requires evil interactions between the SPI and UART drivers to work even partially. The current code in U-Boot is not sufficient to make this work correctly; auto boot is aborted due to corruption in the UART RX channel interrupting it. Instead, move the environment to eMMC, at the end of the second boot sector. This should not conflict with any other eMMC usage, irrespective of whether the board boots from SPI, NAND, or eMMC: if U-Boot is stored in eMMC, it will be stored well below this location. The kernel only uses the general area of the eMMC once booted, not the boot sectors. Boards that are derivatives of Seaboard don't have the muxing issue, and should/could have a separate U-Boot configuration file that does enable SPI if desired. Alternatively, the environment could be stored in NAND flash, but we currently have no driver for that controller.

tegra: flesh out bootcmd 2012-07-07T12:07:18+00:00 Stephen Warren swarren@nvidia.com 2012-05-16T06:21:00+00:00 bea2674ccde5a495710adef62ebd5a294752f59d This implements a useful bootcmd for Tegra. The boot order is: * If USB enabled, USB storage * Internal MMC (SD card or eMMC) * If networking is enabled, BOOTP/TFTP When booting from USB or MMC, the boot script is assumed to be in partition 1 (although this may be overridden via the rootpart variable), both ext2 and FAT filesystems are supported, the boot script may exist in either / or /boot, and the boot script may be named boot.scr.uimg or boot.scr. When booting over the network, it is assumed that boot.scr.uimg exists on the TFTP server. There is less flexibility here since those setting up network booting are expected to need less hand-holding. In all cases, it is expected that the initial file loaded is a U-Boot image containing a script that will load the kernel, load any required initrd, load any required DTB, and finally bootm the kernel.
