[U-Boot] [PATCH V2 12/13] ARM: tegra: add Venice2 (Tegra124) board

Stephen Warren swarren at wwwdotorg.org
Fri Jan 24 01:42:59 CET 2014


From: Tom Warren <twarren.nvidia at gmail.com>

These are the board files for Venice2 (Tegra124), plus the AS3722 PMIC
files. PMIC init will be moved to pmic_common_init later.

This builds/boots on Venice2, SPI/MMC/USB/I2C all work. Audio, display
and WB/LP0 are not supported yet.

v2:
* Convert to Kconfig-style make Makefiles.
* Updated default environment to enable bootcmd_pxe.
* Removed most functional diffs (i.e. other than SoC name, valid values,
  etc.) between include/configs/tegra1[12]4-common.h.
* Deleted PMIC programming code that was disabled; it can be added later
  if it turns out to be useful.
* Fixed boards.cfg sort order.
* Removed unused define CONFIG_TEGRA_USE_EMC_DRAM_SIZE.
* Minor comment cleanup.
