| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch cleans up the Freescale MPC8308RDB Development board support. Things fixed: - Removed unused PCIE2 definitions from configuration - SICR{L,H} defines used for System I/O Configuration Registers values instead of hardcoding - CONFIG_SYS_SCCR_PCIEXP1CM used to enable PCIE clock instead of writing to SCCR from the board code - sleep mode stuff removed as MPC8308 has no support for deep sleep and PMCCR1 register. board_early_init_f() removed. - MPC8308 has no ERRATA for DDR controller so workaround removed - 'assignment in if statement' issues solved - use LBLAWAR_* defines instead of hardcoding Signed-off-by: Ilya Yanok <yanok@emcraft.com> Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
| * e300: increase CONFIG_SYS_BOOTMAPSZ to allow booting large kernelsIra W. Snyder2010-09-23-44/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Newer Linux kernels can overrun the initial memory window used for booting with their BSS area. When this happens, they overwrite the FDT and silently fail to boot. On e300 CPUs, the Linux kernel uses an initial BAT covering the first 256MB of RAM. See arch/powerpc/kernel/head_32.S for details. Increase the value of CONFIG_SYS_BOOTMAPSZ to accommodate the maximum value allowed by Linux. This will allow very large kernels to boot. Signed-off-by: Ira W.

| * ppc4xx: Use common NS16550 driver for PPC4xx UARTStefan Roese2010-09-23-96/+340
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| * ppc4xx: Big header cleanup part 2, mostly PPC405 relatedStefan Roese2010-09-23-80/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This cleanup is done by creating header files for all SoC versions and moving the SoC specific defines into these special headers. This way the common header ppc405.h and ppc440.h can be cleaned up finally. As a part from this cleanup, the GPIO definitions for PPC405EP are corrected. The high and low parts of the registers (for example CONFIG_SYS_GPIO0_OSRL vs. CONFIG_SYS_GPIO0_OSRH) have been defined in the wrong order. This patch now fixes this issue by switching these xxxH and xxxL values. This brings the GPIO 405EP port in sync with all other PPC4xx ports. Signed-off-by: Stefan Roese <sr@denx.de>

| | * cfi_flash: Simplify dynamic flash bank number detectionStefan Roese2010-09-20-12/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch simplifies the use of CONFIG_SYS_MAX_FLASH_BANKS_DETECT. By moving these optional variables and defines into the common code, board specific code is minimized. Currently only the following board use this feature: APC405, IDS8247, TQM834x And IDS8247 doesn't seem to really need this feature, since its not updating the bank number variable at all. So this patch removes the definition of CONFIG_SYS_MAX_FLASH_BANKS_DETECT from this board port. This new framework will be used by the upcoming lwmon5 update as well.

| * da8xx: fixup ARM relocation supportBen Gardiner2010-09-19-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Split the existing dram_init for da8xx when ARM reloc is enabled, like the changes to arch/arm/cpu/arm926ejs/orion5x/dram.c in 0f234d263b17ccf1b8fd776eb8c15b7cdb27a887 by Heiko Schocher <hs@denx.de>. Without these changes gd->ram_size is '0' which leads to incorrect relocation when CONFIG_SYS_ARM_WITHOUT_RELOC is defined and the board does not boot. We use get_ram_size to dynamically calculate the available RAM because it runs on different board version with different ram, as suggested by Heiko in private communication. Tested on a da850evm with 128M of DDR2 installed; with both CONFIG_SYS_ARM_WITHOUT_RELOC defined and undefined.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Traditionally many boards used local definitions for SRAM base address and size (like SRAM_BASE, SRAM_LEN and/or SRAM_SIZE), while the (now) "official" names are CONFIG_SYS_SRAM_BASE and CONFIG_SYS_SRAM_SIZE. The corresponding code in arch/powerpc/lib/board.c was board specific, and has never actually been maintained well. Replace this by feature- specific code and adapt the boards that actually use this. NOTE: there is still a ton of boards using the old #defines, which therefor contain incorrect values in bi_sramstart and bi_sramsize. All respective board maintainers are requested to clean up their respective configurations. Thanks.

* | ppc4xx/fdt/flash: Change fdt_fixup_nor_flash_node() to not rely on cs sizeStefan Roese2010-09-23-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the behaviour of the fdt_fixup_nor_flash_node() function. Now it doesn't patch the size of the "reg" property with the chip-select size, but with the size returned from the new function flash_get_bank_size(). This function will return per weak default the flash size of the bank (bank = chip-select numer) detected by the flash driver. If this does not fit your needs, this function may be overridden by a board specific one. For this the parameters needed to be changed. So I intentionally squashed the PPC4xx stuff using this routine into this patch. Otherwise it would not be git-bisectable anymore. The board specific function for the AMCC/APM Ebony eval board is now included in this patch version.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the MMU hardware to set up 1:1 mappings between physical and virtual addresses. This allows us to bypass the cache when accessing the flash without having to do any physical-to-virtual address mapping in the CFI driver. The virtual memory mappings are defined at compile time through a sorted array of virtual memory range objects. When a TLB miss exception happens, the exception handler does a binary search through the array until it finds a matching entry and loads it into the TLB. The u-boot image itself is covered by a fixed TLB entry which is never replaced. This makes the 'saveenv' command work again on ATNGW100 and other boards using the CFI driver, hopefully without breaking any rules. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
