From 06f60ae3e454e15a410a0d4e96769bf938af8fcb Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Thu, 6 Dec 2012 13:33:17 +0000 Subject: powerpc/mpc83xx: add support for new SPL This adds arch support for PPC mpc83xx to boot "minimal" (4K) SPLs using the new infrastructure. Existing nand_spl targets are updated to deal with the name change from nand_init.c to spl_minimal.c (as in theory this isn't limited to NAND anymore).

Tegra30-specific headers are in arch-tegra30. Note that some of these will be filled in as more T30 support is added (drivers, WB/LP0 support, etc.). A couple of Tegra20 files were changed to support common headers in arch-tegra, also.

For example, after updating SPD with a valid but wrong image, u-boot won't come up due to wrong DDR configuration. By enabling key press method, we can enter debug mode to have a chance to boot without using other tools to recover the board. CONFIG_FSL_DDR_INTERACTIVE needs to be defined in header file. To enter the debug mode by key press, press key 'd' shortly after reset, like one would do to abort auto booting. It is fixed to lower case 'd' at this moment.

This controller is similar to the tegra20 SPI "SFLASH" controller. The difference is that the SLINK controller is a genernal purpose SPI controller and the SFLASH controller is special purpose and can only talk to FLASH devices. In addition there are potentially many instances of an SLINK controller on tegra and only a single instance of SFLASH. Tegra20 is currently ths only version of tegra that instantiates an SFLASH controller. This driver supports basic PIO mode of operation and is configurable (CONFIG_OF_CONTROL) to be driven off devicetree bindings. Up to 4 devices per controller may be attached, although typically only a single chip select line is exposed from tegra per controller so in reality this is usually limited to 1.

Tegra114-specific headers are in arch-tegra114. Note that some of these will be filled in as more T114 support is added (drivers, WB/LP0 support, etc.).
