* config: remove platform CONFIG_SYS_HZ definition part 1/2Rob Herring2013-11-04-1/+0

* config: Add a default CONFIG_SYS_PROMPTRob Herring2013-11-04-1/+0
| | | | | | | | | | The definitions for CONFIG_SYS_PROMPT are varied with little reason other than to display the board name. Over half the definitions are "==> ", so make this the default. The rest of the boards remain unchanged to avoid breaking any external scripts expecting a certain prompt.

* sdhc_boot: Introduce CONFIG_FSL_FIXED_MMC_LOCATION optionFabio Estevam2012-02-12-0/+1
| | | | | | | | | | | | | | | | | | | Since commit 97039ab98 (env_mmc: Allow board code to override the environment address) mmc_get_env_addr is a weak-aliased function in common/env_mmc.c The mmc_get_env_addr implementation that exists at board/freescale/common/sdhc_boot.c is meant to be used only for PowerPC boards, but currently it is being used for all platforms that have CONFIG_ENV_IS_IN_MMC defined. Introduce CONFIG_FSL_FIXED_MMC_LOCATION so that the boards that need to use the mmc_get_env_addr version from board/freescale/common/sdhc_boot.c could activate this config option on their board file. This fixes the retrieval of CONFIG_ENV_OFFSET on non-PowerPC boards.

* powerpc/85xx: introduce and document CONFIG_SYS_CCSRBAR macrosTimur Tabi2011-09-29-14/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce the CONFIG_SYS_CCSRBAR_PHYS_HIGH and CONFIG_SYS_CCSRBAR_PHYS_LOW macros, which contain the high and low portions of CONFIG_SYS_CCSRBAR_PHYS. This is necessary for the assembly-language code that relocates CCSR, since the assembler does not understand 64-bit constants. CONFIG_SYS_CCSRBAR_PHYS is automatically defined from the CONFIG_SYS_CCSRBAR_PHYS_HIGH and CONFIG_SYS_CCSRBAR_PHYS_LOW macros, so it should not be defined in a board header file. Similarly, CONFIG_SYS_CCSRBAR_DEFAULT is defined for each SOC in config_mpc85xx.h, so it should also not be defined in the board header file. CONFIG_SYS_CCSR_DO_NOT_RELOCATE is a "short-cut" macro that guarantees that CONFIG_SYS_CCSRBAR_PHYS is set to the same value as CONFIG_SYS_CCSRBAR_DEFAULT, and so CCSR will not be relocated. Since CONFIG_SYS_CCSRBAR_DEFAULT is locked to a fixed value, multi-stage U-Boot builds (e.g. NAND) are required to relocate CCSR only during the last stage (i.e. the "real" U-Boot). All other stages should define CONFIG_SYS_CCSR_DO_NOT_RELOCATE to ensure that CCSR is not relocated. README is updated with descriptions of all the CONFIG_SYS_CCSRBAR_xxx macros.

* powerpc/85xx: Introduce CONFIG_SYS_EXTRA_ENV_RELOCKumar Gala2010-11-30-2/+3
| | | | | | | | | | | | | | | | | Some systems need to relocate the env_addr pointer early because the location it points to will get invalidated before env_relocate is called. One example is on systems that might use a L2 or L3 cache in SRAM mode and initialize that cache from SRAM mode back to being a cache in cpu_init_r. We set this on the 85xx boards that have support for NAND, SPI, or SDHC/MMC boot support as they use a secondary cache in SRAM mode and need the env_addr pointer relocated since we change from SRAM to normal cache mode in cpu_init_r. Also removed CONFIG_SYS_SPL as its not used anywhere. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* 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.

* mkconfig: change CONFIG_MK_ prefix into plain CONFIG_Wolfgang Denk2010-10-18-4/+4
| | | | | | | | | | | | | | | | | | | | When planning for more generalization and Makefile cleanup it became obvious that the introduction of a separate CONFIG_MK_ name space for config options that were set through scripting in the Makefile was not a good idea. Originally the idea was to provide a script-free approach to supply configuration options - there was no real need for a separate name space. But when we now convert the existing Makefile entries to make use of this approach, it would mean that we have to touch a large number of board config files and add #ifdef / #define sequences to "convert" from the CONFIG_MK_ to the CONFIG_ name space. It seems much cleaner to get rid of this somewhat arbitrary _MK string now for the few boards that actually use it.

* On-chip ROM boot: MPC8536DS supportMingkai Hu2009-09-30-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | The MPC8536E is capable of booting from the on-chip ROM - boot from eSDHC and boot from eSPI. When power on, the porcessor excutes the ROM code to initialize the eSPI/eSDHC controller, and loads the mian U-Boot image from the memory device that interfaced to the controller, such as the SDCard or SPI EEPROM, to the target memory, e.g. SDRAM or L2SRAM, then boot from it. The memory device should contain a specific data structure with control word and config word at the fixed address. The config word direct the process how to config the memory device, and the control word direct the processor where to find the image on the memory device, or where copy the main image to. The user can use any method to store the data structure to the memory device, only if store it on the assigned address. The on-chip ROM code will map the whole 4GB address space by setting entry0 in the TLB1, so the main image need to switch to Address space 1 to disable this mapping and map the address space again. This patch implements loading the mian U-Boot image into L2SRAM, so the image can configure the system memory by using SPD EEPROM.

* NAND boot: MPC8536DS supportMingkai Hu2009-09-30-18/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MPC8536E can support booting from NAND flash which uses the image u-boot-nand.bin. This image contains two parts: a 4K NAND loader and a main U-Boot image. The former is appended to the latter to produce u-boot-nand.bin. The 4K NAND loader includes the corresponding nand_spl directory, along with the code twisted by CONFIG_NAND_SPL. The main U-Boot image just like a general U-Boot image except the parts that included by CONFIG_SYS_RAMBOOT. When power on, eLBC will automatically load from bank 0 the 4K NAND loader into the FCM buffer RAM where CPU can execute the boot code directly. In the first stage, the NAND loader copies itself to RAM or L2SRAM to free up the FCM buffer RAM, then loads the main image from NAND flash to RAM or L2SRAM and boot from it. This patch implements the NAND loader to load the main image into L2SRAM, so the main image can configure the RAM by using SPD EEPROM. In the first stage, the NAND loader copies itself to the second to last 4K address space, and uses the last 4K address space as the initial RAM for stack. Obviously, the size of L2SRAM shouldn't be less than the size of the image used. If so, the workaround is to generate another image that includes the code to configure the RAM by SPD and load it to L2SRAM first, then relocate the main image to RAM to boot up.
