| | | | | | | | | | | | Use __image_copy_end instead of __bss_start for the end of the image to relocate. This is the same as commit 033ca72, but applied to all ARM start.S. This is a more appropriate symbol naming for an image copy & relocate feature, and this also saves a useless copy of data put between __image_copy_end and __bss_start in linker scripts (e.g. relocation information, or MMU initialization tables used only before jumping to the relocated image).

| * ARM: tegra: implement WAR for Tegra114 CPU reset vectorStephen Warren2013-03-14-4/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | A Tegra114 HW bug prevents the main CPU vector from being modified under certain circumstances. Tegra114 A01P and later with a patched boot ROM set the CPU reset vector to 0x4003fffc (end of IRAM). This allows placing an arbitrary jump instruction at that location, in order to redirect to the desired reset vector location. Modify Tegra114's start_cpu() to make use of this feature. This allows CPUs with the patched boot ROM to boot. Based-on-work-by: Jimmy Zhang <jimmzhang@nvidia.com>.

Also, rewrite the C runtime setup and make functions board_init_*() and relocate_code() behave according to normal C semantics (no jumping across the C stack any more, etc).

* Reduce build timesWolfgang Denk2011-11-03-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | U-Boot Makefiles contain a number of tests for compiler features etc. which so far are executed again and again. On some architectures (especially ARM) this results in a large number of calls to gcc. This patch makes sure to run such tests only once, thus largely reducing the number of "execve" system calls. Example: number of "execve" system calls for building the "P2020DS" (Power Architecture) and "qong" (ARM) boards, measured as: -> strace -f -e trace=execve -o /tmp/foo ./MAKEALL <board> -> grep execve /tmp/foo | wc -l Before: After: Reduction: ================================== P2020DS 20555 15205 -26% qong 31692 14490 -54% As a result, built times are significantly reduced, typically by 30...50%.
