* Support legacy multi-type images without FDT section.Nick Spence2008-05-10-3/+2
| | | | | | | | | | | | This patch enables legacy multi-type images containing only a Linux kernel and root file system to be loaded, maintaining compatibility with previous versions of u-boot. This is required when using old image files such as a Linux 2.4 kernel / filesystem. Signed-off-by: Nick Spence <nick.spence@freescale.com> Acked-by: Bartlomiej Sieka <tur@semihalf.com>

* ppc flush_cache: add watch-dog triggering into the loops.Yuri Tikhonov2008-04-29-0/+3
| | | | | | | | | | Some boards (e.g. lwmon5) need rather a frequent watch-dog kicking. Since the time it takes for the flush_cache() function to complete its job depends on the size of data being flushed, one may encounter watch-dog resets on such boards when, for example, download big files over ethernet.

* lib_ppc: Revert "Make MPC83xx one step closer to full relocation."Kim Phillips2008-04-25-1/+0
| | | | | | | | This reverts commit 70431e8a7393b6b793f77957f95b999fc9a269b8 which has proven problematic getting right from the start at least on 83xx and 4xx. Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
* Restore the ability to continue booting after legacy image overwriteMarian Balakowicz2008-04-17-2/+2
| | | | | | | | | | | Before new uImage code was merged, bootm code allowed for the kernel image to get overwritten during decompresion. new uImage introduced a check for image overwrites and refused to boot the image that got overwritten. This patch restores the old behavior. It also adds a warning when the image overwriten is a multi-image file, because in such case accessing componentes other than the first one will fail.

* ppc: Revert patch 70431e8a that used _start instead of CFG_MONITOR_BASEStefan Roese2008-04-09-1/+1
| | | | | | | | | The patch 70431e8a7393b6b793f77957f95b999fc9a269b8 (Make MPC83xx one step closer to full relocation.) doesn't use CFG_MONITOR_BASE anymore. But on 4xx systems _start currently cannot be used for this calculation. So revert back to the original version for now. Signed-off-by: Stefan Roese <sr@denx.de>

| * | mpc8323erdb: fix EEPROM page size and get MAC from EEPROMMichael Barkowski2008-03-28-1/+1
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes eeprom page size so that you can now write more than 64 bytes at a time. It also makes the board take MAC addresses, if found, from EEPROM. User should place up to 4 addresses at offset 0x7f00, for eth{,1,2,3}addr. Any unused addresses should be zero. This group of four six-byte values should have it's CRC at the end. crc32 and eeprom commands can be used to accomplish this. If CRC fails, MAC addresses come from the environment. If CRC succeeds, the environment is overwritten at startup. Signed-off-by: Michael Barkowski <michael.barkowski@freescale.com> Signed-off-by: Kim Phillips <kim.phillips@freescale.com>

* | ppc: Add CFG_MEM_TOP_HIDE option to hide memory area that doesn't get "touched"Stefan Roese2008-03-27-0/+13
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If CFG_MEM_TOP_HIDE is defined in the board config header, this specified memory area will get subtracted from the top (end) of ram and won't get "touched" at all by U-Boot. By fixing up gd->ram_size the Linux kernel should gets passed the now "corrected" memory size and won't touch it either. This should work for arch/ppc and arch/powerpc. Only Linux board ports in arch/powerpc with bootwrapper support, which recalculate the memory size from the SDRAM controller setup, will have to get fixed in Linux additionally. This patch enables this config option on some PPC440EPx boards as a workaround for the CHIP 11 errata. Here the description from the AMCC documentation: CHIP_11: End of memory range area restricted access. Category: 3 Overview: The 440EPx DDR controller does not acknowledge any transaction which is determined to be crossing over the end-of-memory-range boundary, even if the starting address is within valid memory space. Any such transaction from any PLB4 master will result in a PLB time-out on PLB4 bus. Impact: In case of such misaligned bursts, PLB4 masters will not retrieve any data at all, just the available data up to the end of memory, especially the 440 CPU. For example, if a CPU instruction required an operand located in memory within the last 7 words of memory, the DCU master would burst read 8 words to update the data cache and cross over the end-of-memory-range boundary. Such a DCU read would not be answered by the DDR controller, resulting in a PLB4 time-out and ultimately in a Machine Check interrupt. The data would be inaccessible to the CPU. Workaround: Forbid any application to access the last 256 bytes of DDR memory. For example, make your operating system believe that the last 256 bytes of DDR memory are absent. AMCC has a patch that does this, available for Linux. This patch sets CFG_MEM_TOP_HIDE for the following 440EPx boards: lwmon5, korat, sequoia The other remaining 440EPx board were intentionally not included since it is not clear to me, if they use the end of ram for some other purpose. This is unclear, since these boards have CONFIG_PRAM defined and even comments like this: PMC440.h: /* esd expects pram at end of physical memory. * So no logbuffer at the moment. */ It is strongly recommended to not use the last 256 bytes on those boards too. Patches from the board maintainers are welcome. Signed-off-by: Stefan Roese <sr@denx.de>

Convert PPC specific fdt_relocate() to use lmb for allocation of the device tree. Provided a weak function that board code can call to do additional lmb reserves if needed. Also introduce the concept of bootmap_base to specify the offset in physical memory that the bootmap is located at. This is used for allocations of the cmdline, kernel bd, and device tree as they should be contained within bootmap_base and bootmap_base + CFG_BOOTMAPSZ.
