* Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk2010-10-26-2/+1
| | | | | | | | | | | | | | | | | | CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not being able to use "sizeof(struct global_data)" in assembler files. Recent experience has shown that manual synchronization is not reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into GENERATED_GBL_DATA_SIZE which gets automatically generated by the asm-offsets tool. In the result, all definitions of this value can be deleted from the board config files. We have to make sure that all files that reference such data include the new <asm-offsets.h> file. No other changes have been done yet, but it is obvious that similar changes / simplifications can be done for other, related macro definitions as well.

* Rename CONFIG_SYS_INIT_RAM_END into CONFIG_SYS_INIT_RAM_SIZEWolfgang Denk2010-10-26-2/+2
| | | | | | | | | | | | | | | | | | CONFIG_SYS_INIT_RAM_END was a misnomer as it suggests this might be some end address; to make the meaning more clear we rename it into CONFIG_SYS_INIT_RAM_SIZE No other code changes are performed in this patch, only minor editing of white space (due to the changed length) and the comments was done, where noticed. Note that the code for the PATI and cmi_mpc5xx board configurations looks seriously broken.

* ppc4xx/POST: Add board specific UART POST test to lwmon5Stefan Roese2010-10-20-0/+11
| | | | | | | | | Add CONFIG_POST_UART to implement a board specific UART POST test. This is done since lwmon5 needs to set POST_ALWAYS to run this test on each reboot. And we don't want to change the default behavious of this this. Signed-off-by: Stefan Roese <sr@denx.de>
* powerpc: Cleanup BOOTFLAG_* referencesPeter Tyser2010-10-18-8/+0
| | | | | | | | | | | | Now that warm booting is not supported, there isn't a need for the BOOTFLAG_COLD and BOOTFLAG_WARM defines, so remove them. Note that this change makes the board info bd_bootflags field useless. It will always be set to 0, but we leave it around so that we don't break the board info structure that some OSes are expecting to be passed from U-Boot.

* Makefile: move all Power Architecture boards into boards.cfgWolfgang Denk2010-10-18-0/+5
| | | | | | | | | | Clean up Makefile, and drop a lot of the config.mk files on the way. We now also automatically pick all boards that are listed in boards.cfg (and with all configurations), so we can drop the redundant entries from MAKEALL to avoid building these twice.

* Rename TEXT_BASE into CONFIG_SYS_TEXT_BASEWolfgang Denk2010-10-18-1/+1
| | | | | | | | | | | | The change is currently needed to be able to remove the board configuration scripting from the top level Makefile and replace it by a simple, table driven script. Moving this configuration setting into the "CONFIG_*" name space is also desirable because it is needed if we ever should move forward to a Kconfig driven configuration system.

* ppc4xx: Use common ns16550 functions in 4xx UART POST driverStefan Roese2010-10-04-1/+2
| | | | | | | | | | | | | | | | | This patch changes the PPC4xx POST UART driver to use the common NS16550 functions for receiving and sending. Additionally the local function for SoC divisor setup are removed. Instead the functions from arch/powerpc/cpu/ppc4xx/4xx_uart.c are used. This removes code duplication. Also the common CONFIG_SYS_NS16550_COMx defines are now used to describe the POST UART's. And a compile breakage is fixed, introduced by a git merge of the ppc4xx/next branch into master. Now "ppc4xx.h" is moved to "asm/ppc4xx.h". Fixed as well with this patch. Signed-off-by: Stefan Roese <sr@denx.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the PPC4xx UART driver. Instead the common NS16550 driver is used, since all PPC4xx SoC's use this peripheral device. The file 4xx_uart.c now only implements the UART clock calculation function which also sets the SoC internal UART divisors. All PPC4xx board config headers are changed to use this common NS16550 driver now. Tested on these boards: acadia, canyonlands, katmai, kilauea, sequoia, zeus Signed-off-by: Stefan Roese <sr@denx.de>

* video: mb862xx: add option VIDEO_FB_16BPP_WORD_SWAP for IPEK01Wolfgang Grandegger2009-10-31-0/+1
| | | | | | | | | | In 16 bpp mode, the new IPEK01 board only requires swapping of D16 words for D32 accesses due to the diffferent connecting to the GDC bus. This patch introduces the configuration option VIDEO_FB_16BPP_WORD_SWAP, which should be set for all board using the mb862xx in 16 bpp mode. For the IPEK01, VIDEO_FB_16BPP_PIXEL_SWAP should not be set. Signed-off-by: Wolfgang Grandegger <wg@denx.de>

This patch prepares this change and starts a 6 month transition period as follows: - The new "source" command has been added, which implements exactly the same functionlaity as the old "autoscr" command before - The old "autoscr" command name is kept as an alias for compatibility - Command sequences, script files atc. have been adapted to use the new "source" command - Related environment variables ("autoscript", "autoscript_uname") have *not* been adapted yet; these will be renamed resp. removed in a separate patch when the support for the "autoscr" command get's finally dropped.

* Fix printf() format problems with configurable promptsWolfgang Denk2008-07-31-1/+2
| | | | | | | | | | | | | | | U-Boot allows for configurable prompt strings using the CONFIG_AUTOBOOT_PROMPT resp. CONFIG_MENUPROMPT definitions. So far, the assumption was that any such user defined problts would contain exactly one "%d" format specifier. But some boards did not. To allow for flexible boot prompts without adding too complex code we now allow to specify the whole list of printf() arguments in the user definition. This is powerful, but requires a responsible user who really understands what he is doing, as he needs to know for exanple which variables are available in the respective context.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Limit the rate of h/w watch-dog triggering on the LWMON5 board by the CONFIG_WD_MAX_RATE value. Note that an earlier version of this patch which used microseconds instead of ticks dis not work. The problem was that we used usec2ticks() to convert microseconds into ticks. usec2ticks() uses get_tbclk(), which in turn calls get_sys_info(). It turns out that this function does a lot of prolonged operations (like divisions) which take too much time so we do not trigger the watchdog in time, and it resets the system.

* | ppc: Add CFG_MEM_TOP_HIDE option to hide memory area that doesn't get "touched"Stefan Roese2008-03-27-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
