* lib_ppc/interrupts.c: make board_show_activity() a weak functionWolfgang Denk2008-09-09-1/+6
| | | | | | | This allows to use show_activity() without having to define an empty board_show_activity() function. Signed-off-by: Wolfgang Denk <wd@denx.de>
* bootm: refactor do_reset and os boot function argsKumar Gala2008-08-26-7/+4
| | | | | | | | | | | | There is no need for each OS specific function to call do_reset() we can just do it once in bootm. This means its feasible on an error for the OS boot function to return. Also, remove passing in cmd_tbl_t as its not needed by the OS boot functions. flag isn't currently used but might be in the future so we left it alone.

* fdt: refactor initrd related codeKumar Gala2008-08-26-26/+2
| | | | | | | | | Created a new fdt_initrd() to deal with setting the initrd properties in the device tree and fixing up the mem reserve. We can use this both in the choosen node handling and lets us remove some duplicated code when we fixup the initrd info in bootm on PPC. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* fdt: refactor fdt resize codeKumar Gala2008-08-26-28/+4
| | | | | | | Move the fdt resizing code out of ppc specific boot code and into common fdt support code. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* bootm: move lmb into the bootm_headers_t structureKumar Gala2008-08-26-1/+1
| | | | | | | | To allow for persistent state between future bootm subcommands we need the lmb to exist in a global state. Moving it into the bootm_headers_t allows us to do that. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* bootm: refactor fdt locating and relocation codeKumar Gala2008-08-26-484/+8
| | | | | | | Move the code that handles finding a device tree blob and relocating it (if needed) into common code so all arch's have access to it. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* bootm: refactor ramdisk locating codeKumar Gala2008-08-26-11/+5
| | | | | | | | Move determing if we have a ramdisk and where its located into the common code. Keep track of the ramdisk start and end in the bootm_headers_t image struct. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* bootm: refactor entry point codeKumar Gala2008-08-26-19/+3
| | | | | | | Move entry point code out of each arch and into common code. Keep the entry point in the bootm_headers_t images struct. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* Consolidate strmhz() implementationHaavard Skinnemoen2008-08-21-13/+0
| | | | | | | | | | ARM, i386, m68k and ppc all have identical implementations of strmhz(). Other architectures don't provide this function at all. This patch moves strmhz() into lib_generic, reducing code duplication and providing a more unified API across architectures. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
* Update linux bootm to support ePAPR client interfaceKumar Gala2008-08-19-10/+23
| | | | | | | | The ePAPR spec has some subtle differences from the current device tree based boot interface to the powerpc linux kernel. The powerpc linux kernel currently ignores the differences that ePAPR specifies. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* NAND boot: MPC8313ERDB supportScott Wood2008-08-12-2/+2
| | | | | | | | | Note that with older board revisions, NAND boot may only work after a power-on reset, and not after a warm reset. I don't have a newer board to test on; if you have a board with a 33MHz crystal, please let me know if it works after a warm reset. Signed-off-by: Scott Wood <scottwood@freescale.com>
* Fix fallout from autostart revertKumar Gala2008-08-12-4/+1
| | | | | | | | The autostart revert caused a bit of duplicated code as well as code that was using images->autostart that needs to get removed so we can build again. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* Fix printf errors.Andrew Klossner2008-07-09-4/+4
| | | | | | | | | | | | The compiler will help find mismatches between printf formats and arguments if you let it. This patch adds the necessary attributes to declarations in include/common.h, then begins to correct the resulting compiler warnings. Some of these were bugs, e.g., "$d" instead of "%d" and incorrect arguments. Others were just annoying, like int-long mismatches on a system where both are 32 bits. It's worth fixing the annoying errors to catch the real ones. Signed-off-by: Andrew Klossner <andrew@cesa.opbu.xerox.com>

* Resize device tree to allow space for board changes and the chosen nodeAndy Fleming2008-06-28-8/+58
| | | | | | | | | | | | | Current code requires that a compiled device tree have space added to the end to leave room for extra nodes added by board code (and the chosen node). This requires that device tree creators anticipate how much space U-Boot will add to the tree, which is absurd. Ideally, the code would resize and/or relocate the tree when it needed more space, but this would require a systemic change to the fdt code, which is non-trivial. Instead, we resize the tree inside boot_relocate_fdt, reserving either the remainder of the bootmap (in the case where the fdt is inside the bootmap), or adding CFG_FDT_PAD bytes to the size.

* Change lmb to use phys_size_t/phys_addr_tBecky Bruce2008-06-12-7/+9
| | | | | | | | | | | This updates the lmb code to use phys_size_t and phys_addr_t instead of unsigned long. Other code which interacts with this code, like getenv_bootm_size() is also updated.

In the future we will move to doing more "dynamic" LAW allocation since the majority of users dont really care about what LAW number they are at.

* 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.

* 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.

| * | 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>
