| * relocation: Do not relocate NULL pointers.Joakim Tjernlund2009-10-08-24/+48
| | | | | | | | | | | | | | | | | | | | NULL is an absolute value and should not be relocated. After this correction code like: void weak_fun(void) __attribute__((weak)); printf("weak_fun:%p\n", weak_fun); will still print null after relocation.

| * 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * 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>

| | | | | | | | | | | | | | | | | | | | Certain ppc compilers are known not to generate the .fixup section properly. The .fixup section is necessary to create a relocatable U-Boot image.

* | tqm5200: Correct comment and code in post_hotkeys_pressed.Detlev Zundel2009-10-08-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the code and the comment according to the original intent of doing an intensive memory test when PSC6_3 is pulled low on the STK52xx. Notably PORT_CONFIG will be overridden with this correct code now, so beware. The original code only worked by coincidence depending on the PORT_CONFIG setting from the header file. The new code was tested to ensure that the (undocumented) memory test still works on the STK52x.

| | | | | | | | | | | | | | | | | | | | Commit 054197ba and later fixes used an array to initialize some of the MDDRC parameters; however, the use of an array turned out to be a bad idea as it was not possible to correlate structure entries to array indices in readable and reliable way.

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.

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.

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.
