2010-05-26Coding style cleanup, update CHANGELOG.Wolfgang Denk
Signed-off-by: Wolfgang Denk <wd@denx.de>
2010-05-06sc520: Fix minor DRAM Controller Setup bugGraeme Russ
Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06sc520: Update to new AMD CopyrightGraeme Russ
AMD recently changed the licensing of the RAM sizing code to the GPLv2 (or at your option any later version) Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06sc520: Board Specific PCI InitGraeme Russ
Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06sc520: Move PCI defines to PCI include fileGraeme Russ
Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06sc520: Allow boards to override udelayGraeme Russ
If the board has a high precision mico-second timer, it maked sense to use it instead of the on-chip one Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Fix support for booting bzImageGraeme Russ
Add support for newer (up to 2.6.33) kernels Add zboot command which takes the address of a bzImage as its first argument and (optionally) the size of the bzImage as the second argument (the second argument is needed for older kernels which do not include the bzImage size in the header) Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Provide weak PC/AT compatibility setup functionGraeme Russ
It is possibly to setup x86 boards to use non-PC/AT configurations. For example, the sc520 is an x86 CPU with PC/AT and non-PC/AT peripherals. This function allows the board to set itself up for maximum PC/AT compatibility just before booting the Linux kernel (the Linux kernel 'just works' if everything is PC/AT compliant) Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Use CONFIG_SERIAL_MULTIGraeme Russ
Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Fix copying of Real-Mode code into RAMGraeme Russ
Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Pass relocation offset into Global DataGraeme Russ
In order to locate the 16-bit BIOS code, we need to know the reloaction offset. Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Move GDT to a safe location in RAMGraeme Russ
Currently, the GDT is either located in FLASH or in the non-relocated U-Boot image in RAM. Both of these locations are unsafe as those locations can be erased during a U-Boot update. Move the GDT into the highest available memory location and relocate U-Boot to just below it Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Add RAM bootstrap functionalityGraeme Russ
Add a parameter to the 32-bit entry to indicate if entry is from Real Mode or not. If entry is from Real Mode, execute the destructive 'sizer' routine to determine memory size as we are booting cold and running in Flash. If not entering from Real Mode, we are executing a U-Boot image from RAM and therefore the memory size is already known (and running 'sizer' will destroy the running image) There are now two 32-bit entry points. The first is the 'in RAM' entry point which exists at the start of the U-Boot binary image. As such, you can load u-boot.bin in RAM and jump directly to the load address without needing to calculate any offsets. The second entry point is used by the real-to-protected mode switch This patch also changes TEXT_BASE to 0x6000000 (in RAM). You can load the resulting image at 0x6000000 and simple go 0x6000000 from the u-boot prompt Hopefully a later patch will completely elliminate any dependency on TEXT_BASE like a relocatable linux kernel (perfect world) Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Split sc520 memory sizing versus reportingGraeme Russ
This patch allows the low-level assembler boot-strap to obtain the RAM size without calling the destructive 'sizer' routine. This allows boot-strapping from a U-Boot image loaded in RAM Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Fix sc520 memory size reportingGraeme Russ
There is an error in how the assembler version of the sc520 memory size reporting code works. As a result, it will only ever report at most the size of one bank of RAM Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Fix do_go_exec()Graeme Russ
This was broken a long time ago by a49864593e083a5d0779fb9ca98e5a0f2053183d which munged the NIOS and x86 do_go_exec() Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Add register dump to crash handlersGraeme Russ
Shamelessly steal the Linux x86 crash handling code and shove it into U-Boot (cool - it fits). Be sure to include suitable attribution to Linus Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Fix MMCR AccessGraeme Russ
Change sc520 MMCR Access to use memory accessor functions Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: #ifdef out getenv_IPaddr()Graeme Russ
Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-05-06x86: Add unaligned.hGraeme Russ
Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2010-04-13i386: Move cpu/i386/* to arch/i386/cpu/*Peter Tyser
Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
2010-04-13Move architecture-specific includes to arch/$ARCH/include/asmPeter Tyser
This helps to clean up the include/ directory so that it only contains non-architecture-specific headers and also matches Linux's directory layout which many U-Boot developers are already familiar with. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
2010-04-13Move lib_$ARCH directories to arch/$ARCH/libPeter Tyser
Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk This change is intended to clean up the top-level directory structure and more closely mimic Linux's directory organization. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
