* ARM: tegra: clean up lowlevel entryLucas Stach2016-01-181-9/+2
| | | | | | | | | | The lowlevel startup function jumps directly to the main cluster if we are already running there. This allows for a significant cleanup of the board startup code by directly using the FDT address available there.

| | | | | | | | | | | | | | This file originates in Linux. Linux has it under include/linux/ directory since commit dccd2304cc90. Let's move it to the same place as well in barebox.

* Documentation: remove doxygen documentationSascha Hauer2014-06-261-37/+0
| | | | | | | The doxygen documentation is long outdated. Remove it. It will be replaced with sphinx based documentation later. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* tegra: disable more lowlevel unsafe switch optimizationsLucas Stach2014-04-231-1/+3
| | | | | | | | | | | | | | fno-jump-tables isn't enough to guard against gcc switch optimizations that are unsafe to use in code that runs before relocation. The switch-tree-conversion opt pass may generate lookup tables that are placed in the data section and accessed via absolute adressing, which fails prior to relocation.

* ARM: Make ENTRY_FUNCTION more robustSascha Hauer2013-12-101-3/+1
| | | | | | | | | | An entry function should begin with a exception header. For this to work properly the entry function should not contain any code which gcc might put before the header. To make this sure change the ENTRY_FUNCTION macro so that it generates one function which only contains the exception header and a second function which contains the original body of the entry function.

* tegra: switch to multi imageLucas Stach2013-10-022-0/+38
| | | | | | | | | | | To keep things clean I removed all support for the old way to build images. There is now a single tegra_v7 defconfig which builds both supported Tegra boards as images. The new image generation also paves the way for integration of the tegra-cbootimage tool to produce directly flashable images.

* tegra: ac100: delete custom KconfigLucas Stach2013-10-021-7/+0

* Set model and hostname at boardlevelSascha Hauer2013-08-161-2/+0
| | | | | | | | | | | | With multiboard support the compiletime generated BOARDINFO string gets more and more meaningless. This removes it from Kconfig and replaces it with a variable that can be set at boardlevel. Also many boards have a standard setting for the hostname in the environment. This patch also moves the standard to C code by calling barebox_set_hostname(). Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * tegra: add generic debug UART supportLucas Stach2013-04-142-40/+0
| | | | | | | | | | | | | | | | | | | | ODMdata tells us which UART to use for debugging purposes. This is agreed upon in both the upstream Linux kernel and U-Boot, so do it the same way in barebox.

| * tegra: add common lowlevel startupLucas Stach2013-04-142-11/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | All Tegra20 boards have a common startup sequence. Also there is an agreement on how to find out about the installed amount of RAM and other information needed by early startup. So as there is really no need to do any lowlevel stuff per board, we can just do it at the ARCH level. This also enables the first stage loading of barebox by detecting the currently running CPU and booting the main CPU cluster if neccesary.
