From 29235b73373f28f2516d2eafbf6ec76ecf8051a3 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Wed, 5 Feb 2014 20:49:21 -0700 Subject: ARM: rpi_b: convert to use distro defaults Modify the rpi_b board to include the "distro defaults" header, so that all the config options distros expect are enabled. Remove any #defines that enable the same options from the rpi_b.h.

However, the user may wish to customize the environment. We know that the SD card must be present, since that's where the boot ROM has loaded U-Boot from. So, load uEnv.txt from there early during boot. This allows the user to e.g. customize boot_targets, in order to automatically select network boot.

Since some gpio input's are read to detect the board revision. But with this patch above, the clocks to the GPIO subsystems are not enabled per default any more. The GPIO banks need to be configured specifically now.

It unfortunately has had a impact on size on SPL as well. For example on SDP4430, 32032 bytes before/MLO 35416 bytes after/MLO With this mentioned commit, MLO stops booting on SDP4430 as only 32K is accessible for non-secure (bootloader) s/w on GP devices and the size increase to 56K fails boot. On the latest u-boot commit e7be18225fbea76d1f0034b224f0d1e60f07cfcf, MLO is now at size 35592 bytes, However, I2C is not necessary for SPL to function as we use SR_I2C for controlling the PMIC. Disabling I2C reduces MLO to 32224 bytes which allows OMAP4 GP platform to boot up. Since this is common for all OMAP4 platforms, remove the need for I2C for SPL builds in the common config.

This will aid in a future patch which will create a common header e.g. config_distro_bootcmd.h. While at it, enable booting from extlinux.conf using the sysboot command. The iteration and componentization currently makes a little more sense for Tegra than RPi, but I'd still like to keep the two as similar as possible. USB and networking support is coming to the RPi in due course, and it'll all make more sense then anyway.
