| * x86: Add support for specifying an initrd with the zboot commandGabe Black2011-12-191-4/+19
| | | | | | | | | | | | | | | | | | | | | | 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.

| * x86: Refactor the zboot innards so they can be reused with a vboot imageGabe Black2011-12-193-90/+122
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If vboot successfully verifies a kernel, it will leave it in place and basically ready to boot. The zeropage table which is part of the x86 boot protocol is at the end of the kernel, though, instead of the beginning, and because the image is already in place there's no need to copy it around. This change refactors the code which implements the zboot command so that the configuration of the zeropage table and loading the pieces of the kernel into memory are done separately. Also, because the command line goes before the zeropage table in vboot which is somewhat incompatible with the normal protocol, where to put the command line is a now a parameter instead of being hard coded.

| * x86: Add infrastructure to extract an e820 table from the coreboot tablesGabe Black2011-12-191-1/+37
| | | | | | | | | | | | | | | | Also approximate the size of RAM using the largest RAM address available in the tables. There may be areas which are marked as reserved which are actually at the end of RAM. Signed-off-by: Gabe Black <gabeblack@chromium.org>
| * x86: Add support for booting Linux using the 32 bit boot protocolGabe Black2011-12-193-17/+62
| | | | | | | | | | | | | | | | | | This change conditionally modifies the zboot command so that it can use the 32 bit boot protocol. This is necessary because the 16 bit realmode entry point assumes that it can call BIOS services which neither coreboot nor u-boot provide. Signed-off-by: Gabe Black <gabeblack@chromium.org>
| * x86: Clean up the x86 zimage code in preparation to extend itGabe Black2011-12-192-58/+45
| | | | | | | | | | | | | | | | This change cleans up some formatting issues in the zimage handling code, and converts it from using offsets added to a base pointer to using the available structure definitions which were already being included. Signed-off-by: Gabe Black <gabeblack@chromium.org>
| * x86: Import code from coreboot's libpayload to parse the coreboot tableGabe Black2011-12-197-0/+620
| | | | | | | | | | | | | | | | | | | | | | | | | | This change also forces the lib_sysinfo structure to be in the .data section. Otherwise it ends up in the .bss section. U-boot assumes that it doesn't need to copy it over during relocation, and instead fills that whole section with zeroes. If we really were booting from ROM that would be appropriate, but we need some information from the coreboot tables (memory size) before then and have to fill that structure before relocation. We skirt u-boot's assumption by putting this in .data where it assumes there is still read only but non-zero data. Signed-off-by: Gabe Black <gabeblack@chromium.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 2f3427c added noop cache functions implementation for arm926ejs to fix compilation of drivers depending on these functions (DaVinci EMAC in particular). Unfortunately, the bug was introduced: noop implementation calls dcache_disable which calls flush_dcache_all which in turn calls dcache_disable thus creating an infinite loop. This patch removes noop implementation for flush_dcache_all, we already have default one in arch/arm/lib/cache.c and it should be used instead.

* powerpc/bootm: Flush ramdisk and device tree image when booting on MPKumar Gala2011-12-121-6/+16
| | | | | | | | | | | | | We already flush the kernel image after we've loaded it to ensure visiblity to the other cores. We need to do the same thing for the ramdisk and device tree images. In AMP boot scenarios we might not be HW cache coherent with the secondary core that we are loading and setting the ramdisk and device tree up for. Thus we need to ensure we've flushed the regions of memory utilized by ramdisk and device tree so the loadding and any modifications (from decompression or fdt updates) are made visible to the secondary cores.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | U-boot itself generally builds with -nostdinc. This is because the bootloader needs to be completely standalone. In the sandbox arch though, we need a little bit of code to glue the u-boot world to the host operating system, and we need to be able to access the host libc's headers in order to do so. Currently, we're using -I/usr/include to workaround the global -nostdinc, but that doesn't work for everyone and for all headers. Instead, let's filter out -nostdinc when building the os.c code. Without this patch, some distros hit errors such as: ---8<--- In file included from /usr/include/fcntl.h:27:0, from os.c:22: /usr/include/features.h:323:26: fatal error: bits/predefs.h: No such file or directory --->8--- Signed-off-by: Andreas Bießmann <biessmann@corscience.de> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* M28: Cleanup memsize.o OOT buildMarek Vasut2011-12-093-23/+9
| | | | | | | | | | | | | | | | The current way memsize.c is built just made a symlink into the directory with SPL and then compiled it like any other file there. This was bad as that broke the out-of-tree build. The new way introduced in this patch uses the standard spl/Makefile methods (CONFIG_SPL_LIBCOMMON_SUPPORT / CONFIG_SPL_LIBGENERIC_SUPPORT) to let files in common/ be built. Because common/Makefile says memsize.c is always built (SPL and non-SPL build), this fixes our issue with memsize.c out-of-tree build.

Here we split the initialization of CP15 into a separate call, which can be performed later if required. Once the main CPU is running, you should call cpu_init_cp15() to perform this init as early as possible. Existing ARMv7 boards which define CONFIG_SKIP_LOWLEVEL_INIT should not need to change, this CP15 init is still skipped in that case. The only impact for these boards is that the cpu_init_cp15() will be available even if it is never used on these boards.

| | | | | | | | | | | | | | | | | The Tegra2 boot path is more complicated than it needs to be. Since we want to move to building most of U-Boot with ARMv7 and only a small part with ARMv4T (for AVP) it should be as simple as possible. This makes tegra2_start() into a simple function which either does AVP init or A9 init depending on which core is running it. Both cores now following the same init path, beginning at _start, and the special Tegra2 boot path code is no longer required. Only two files need to be built for ARMv4T, and this is handled in the Tegra2 CPU Makefile. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
* tegra2: Add arch_cpu_init() to fire up Cortex-A9Simon Glass2011-12-092-0/+21
| | | | | | | | | | | | | We want to move away from a special Tegra2 start-up, and just use arch_cpu_init() instead. However, if we run board_init_f() from boot we need to build it for ARMv4T, since the Tegra's AVP start-up CPU does not support ARMv7. The effect of this is to do the AVP init earlier, and in arch_cpu_init(), rather that board_early_init_f().

* powerpc: Minimal private libgcc to build on DebianKyle Moffett2011-12-074-1/+159
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Standard Debian powerpc and powerpcspe systems only include hard-float libgcc in their native compilers, which causes scary build warnings when building U-Boot. Debian and other PowerPC-supporting distributions used to provide libgcc and other libraries in a "nof" (soft-float) form in the "multilib" packages. As they were completely unused by the distribution and therefore tended to be very buggy it was decided to save some time on the part of the maintainers and build-servers by removing them. Admittedly, right now the linker warnings do not indicate any problems, as the included routines do not use any floating point at all. The concern is that if floating-point code were ever added it might cause hard-float code to be unexpectedly included in U-Boot without generating a hard error. This would cause unexplained crashes or indeterminate results at runtime. The easiest way to resolve this is to borrow the routines that U-Boot needs from the Linux kernel, which has the same issue. Specifically, the routines are: _ashldi3(), _ashrdi3(), and _lshrdi3(). They were borrowed from arch/powerpc/kernel/misc_32.S as of v2.6.38-rc5, commit 85e2efbb1db9a18d218006706d6e4fbeb0216213, and are GPLv2+. The Makefile framework was copied from the U-Boot ARM port.
