* 85xx: Ensure BSS segment isn't linked at address 0Peter Tyser2009-10-08-0/+11
| | | | | | | | | | | | | | | | When U-Boot is relocated from flash to RAM pointers are modified accordingly. However, pointers initialzed with NULL values should not be modified so that they maintain their intended NULL value. If the BSS segment is linked at address 0 its address will not be updated as necessary during relocation. This is a temporary workaround. The end goal is to add support to U-Boot to dynamically locate the BSS at an arbitrary address at runtime. When the ability to fixup the BSS inteligently is added, this workaround can be removed and the 85xx link script can put the BSS at a fixed address at link time.

* ppc: Remove reloc_off field from global_data structurePeter Tyser2009-10-03-2/+2
| | | | | | | | | | | | | | | Now that proper relocation is supported, the reloc_off field is no longer necessary. Note that the location of the standalone application jump table pointer in the global data structure is affected by this change, breaking execution of standalone applications compiled for previous versions of U-Boot. We therefore increment XF_VERSION to 6 Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Wolfgang Denk <wd@denx.de>
* arm/microblaze/nios/nios2/sh: Remove relocation fixupsPeter Tyser2009-10-03-7/+17
| | | | | | | | | | | | | | | | | These architectures don't need relocation fixups, so reduce their codesize a bit by defining CONFIG_RELOC_FIXUP_WORKS. Also remove the reloc_off field from their global data structures as it is no longer needed. Note that the location of the standalone application jump table pointer in the global data structure is affected by this change, breaking execution of standalone applications compiled for previous versions of U-Boot. We will therefore increment XF_VERSION in the next commit, which also touches this area. Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Wolfgang Denk <wd@denx.de>
* Conditionally perform common relocation fixupsPeter Tyser2009-10-03-5/+41
| | | | | | | | | | | Add #ifdefs where necessary to not perform relocation fixups. This allows boards/architectures which support relocation to trim a decent chunk of code. Note that this patch doesn't add #ifdefs to architecture-specific code which does not support relocation. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>

| | | | | | | | | | Certain ppc compilers are known not to generate the .fixup section properly. The .fixup section is necessary to create a relocatable U-Boot image. A basic check for the existence of the .fixup section should hopefully catch the majority of broken compilers which don't support relocation. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>

| * On-chip ROM boot: MPC8536DS supportMingkai Hu2009-09-30-1/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MPC8536E is capable of booting from the on-chip ROM - boot from eSDHC and boot from eSPI. When power on, the porcessor excutes the ROM code to initialize the eSPI/eSDHC controller, and loads the mian U-Boot image from the memory device that interfaced to the controller, such as the SDCard or SPI EEPROM, to the target memory, e.g. SDRAM or L2SRAM, then boot from it. The memory device should contain a specific data structure with control word and config word at the fixed address. The config word direct the process how to config the memory device, and the control word direct the processor where to find the image on the memory device, or where copy the main image to. The user can use any method to store the data structure to the memory device, only if store it on the assigned address. The on-chip ROM code will map the whole 4GB address space by setting entry0 in the TLB1, so the main image need to switch to Address space 1 to disable this mapping and map the address space again. This patch implements loading the mian U-Boot image into L2SRAM, so the image can configure the system memory by using SPD EEPROM.

| * NAND boot: MPC8536DS supportMingkai Hu2009-09-30-18/+307
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MPC8536E can support booting from NAND flash which uses the image u-boot-nand.bin. This image contains two parts: a 4K NAND loader and a main U-Boot image. The former is appended to the latter to produce u-boot-nand.bin. The 4K NAND loader includes the corresponding nand_spl directory, along with the code twisted by CONFIG_NAND_SPL. The main U-Boot image just like a general U-Boot image except the parts that included by CONFIG_SYS_RAMBOOT. When power on, eLBC will automatically load from bank 0 the 4K NAND loader into the FCM buffer RAM where CPU can execute the boot code directly. In the first stage, the NAND loader copies itself to RAM or L2SRAM to free up the FCM buffer RAM, then loads the main image from NAND flash to RAM or L2SRAM and boot from it. This patch implements the NAND loader to load the main image into L2SRAM, so the main image can configure the RAM by using SPD EEPROM. In the first stage, the NAND loader copies itself to the second to last 4K address space, and uses the last 4K address space as the initial RAM for stack. Obviously, the size of L2SRAM shouldn't be less than the size of the image used. If so, the workaround is to generate another image that includes the code to configure the RAM by SPD and load it to L2SRAM first, then relocate the main image to RAM to boot up.

| * sbc8548: reclaim wasted sector in boot flashPaul Gortmaker2009-09-30-4/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By nature of being based off the MPC8548CDS board, this board inherited an ENV_SIZE setting of 256k. But since it has a smaller flash device (8MB soldered on), it has a native sector size of 128k, and hence the ENV_SIZE was causing 2 sectors to be used for the environment. By removing the unused sector, we can push TEXT_BASE up closer to the end of address space and reclaim that sector for any other application. This also fixes the mismatch between TEXT_BASE and MONITOR_LEN reported by Kumar earlier. Since this board also supports the ability to boot off the 64MB SODIMM flash, this change is forward looking with that in mind; i.e. the settings for MONITOR_LEN and ENV_SIZE will work when the 512k sectors of the SODIMM flash are used for alternate boot in the future.
