2012-01-18X86: Implement arch_phys_memset so that it can wipe memory above 4GBGabe Black
Implement arch_phys_memset so that it can set memory at physical addresses above 4GB using PAE paging. Because there are only 5 page tables in PAE mode, 1 PDPT and 4 PDTs, those tables are statically allocated in the BSS. The tables must be 4K page aligned and are declared that way, and because U-Boot starts as 4K aligned and the relocation code relocates it to a 4K aligned address, the tables work as intended. While paging is turned on, all 4GB are identity mapped except for one 2MB page which is used as the window into high memory. This way, U-Boot will continue to work as expected when running code that expects to access memory freely, but the code can still get at high memory through its window. The window is put at 2MB so that it's 2MB page aligned, low in memory to be out of the way of things U-Boot is likely to care about, and above the lowest 1MB where lots of random things live. BUG=chrome-os-partner:7579 TEST=From the original, larger patch: Built and booted on Lumpy, Stumpy, and Kaen. Looked at the log to see that the regions in high memory are listed as cleared. Artificially injected a range to "clear" with 0xA5 and then 0x5A which was over the framebuffer and covered part or all of the screen on Lumpy. Verified that the screen was partially or completely filled with an appropriate looking color. Had U-Boot print the PDTs it was generating to verify that the high address bits were preserved. Identity mapped only some of memory and verified that things that should be mapped were accessible and things that shouldn't be weren't.

2012-01-18X86: Fix some minor bugs in the code that picks a relocation addressGabe Black
When this code picked an area for U-Boot to relocate to, it was making sure that there was enough space for U-Boot's various sections. It wasn't taking into account the space needed for the heap and stack, however, so if it happened to pick a very small region those areas might overlap with something they shouldn't. This change fixes that. Also, this change replaces the ROUND macro with the new rounddown introduced in a previous change. It was assumed that ROUND rounded down, in contrast to the other rounding function in common.h, roundup. It turns out that ROUND rounds up even more agressively than roundup. If the value being rounded is already exactly a multiple of the rounding amount, ROUND will still increase it to the next multiple. Because the region U-Boot had been choosing has plenty of space, there should be no functional difference with this change.

2011-11-22Add support for specifying an initrd with the zboot commandGabe Black
This change finishes plumbing the initrd support built into the zboot mechanism out to the command interface. It also fixes a bug in the command declaration where the kernel size could be passed as an optional second parameter but not enough arguments were allowed. BUG=chrome-os-partner:6715 TEST=Built and booted on a Lumpy with the U-Boot command line exposed. Used the Linux kernel in the system partition and the initramfs used for recovery to boot the system. Observed that the recovery scripts in the initramfs ran. The hardest part about implementing this change was testing because it took many attempts to build/find an initrd/initramfs and command line that would actually work. I'm confident the problems I had were from not knowing how to set up or use an initramfs properly, not from the U-Boot support itself.

2011-11-22UPSTREAM: Reduce build timesWolfgang Denk
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%.
