* ppc4xx: Fix 4xx enet driver to support 460GT EMAC2+3Stefan Roese2008-04-03-3/+13
| | | | | | | | This patch fixes a problem with the RGMII setup of the 460GT. The 460GT has 2 RGMII instances and we need to configure the 2nd RGMII instance for the EMAC2+3 channels. Signed-off-by: Stefan Roese <sr@denx.de>

| | | | | | | | | Canyonlands (460EX) shares the first PCIe interface with the SoC SATA interface. This usage can be configured with the jumper J6. This patch displays the current configuration upon bootup and changes the PCIe init loop, to only initialize the availabel PCIe slots. Signed-off-by: Stefan Roese <sr@denx.de>

* ppc4xx: Enable ECC on LWMON5Stefan Roese2008-03-27-75/+21
| | | | | | | | | | | Since all ECC related problems seem to be resolved on LWMON5, this patch now enables ECC support. We have to write the ECC bytes by zeroing and flushing in smaller steps, since the whole 256MByte takes too long for the external watchdog. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Updates to Korat-specific codeLarry Johnson2008-03-27-75/+463
| | | | | | | | | | | | | | | | This patch contains updates for changes for the Korat PPC440EPx board. These changes include: (1) Support for "permanent" and "upgradable" copies of U-Boot, as described in the new "doc/README.korat" file; (2) a new memory map for the registers in the board's CPLD; (3) a revised format for manufacturer's data in serial EEPROM; and (4) changes to track updates to U-Boot for the Sequoia board.

* ppc4xx: PPC405EP Set EMAC noise filter bitsMarkus Brunner2008-03-27-1/+1
| | | | | | | | | This bug was introduced with commit aee747f19b460a0e9da20ff21e90fdaac1cec359 which enabled CFG_4xx_GPIO_TABLE for PPC405 and unintentionally disabled the setting of the emac noise filter bits for PPC405EP when CFG_4xx_GPIO_TABLE is set.

* ppc4xx: Reconfigure PLL for 667MHz processor for PPC440EPxMike Nuss2008-03-27-1/+99
| | | | | | | | | | | | On PPC440EPx without a bootstrap I2C EEPROM, the PLL can be reconfigured after startup to change the speed of the clocks. This patch adds the option CFG_PLL_RECONFIG. If this option is set to 667, the CPU initialization code will reconfigure the PLL to run the system with a CPU frequency of 667MHz and PLB frequency of 166MHz, without the need for an external EEPROM.

* ppc: Add CFG_MEM_TOP_HIDE option to hide memory area that doesn't get "touched"Stefan Roese2008-03-27-1/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | The routine ft_board_setup() configures the EBC NOR mappings for the Linux physmap_of driver. Since on 460EX/GT we remap the FLASH from 0x4.fc00.0000 to 0x4.cc00.0000 because of the max. 16MByte boot-CS problem, we need to pass the corrected address here too.

| * | Update SVR numbers to expand supportAndy Fleming2008-03-26-50/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FSL has taken to using SVR[16:23] as an SOC sub-version field. This is used to distinguish certain variants within an SOC family. To account for this, we add the SVR_SOC_VER() macro, and update the SVR_* constants to reflect the larger value. We also add SVR numbers for all of the current variants. Finally, to make things neater, rather than use an enormous switch statement to print out the CPU type, we create and array of SVR/name pairs (using a macro), and print out the CPU name that matches the SVR SOC version.
