2010-12-08db8500: Move cpu identifying function to SoC codeJoakim Axelsson
Moved u8500_is_earlydrop() and cpu_is_u8500*() to include/asm-arm/arch-db8500/cpu.h. They are kept in cpu.h as the functions are very small and should be inlined with each use of them. The final binary actually also became around 100 bytes smaller.

2010-11-19U8500: Removed duplicates of common.h and gpio.hMichael Brandt
common.h and gpio.h were present in the u8500 board directory and in the SoC include directory include/asm-arch/arch-stw8500. This patch removes the duplicates in the board directory and replaces all "common.h" and "gpio.h" with <asm/arch/common.h> and <asm/arch/gpio.h>, respectively.

2010-08-31Move modem parameter partition to start of memory.Sebastian Rasmussen
Since memory sizes vary, addresses at the end of the memory vary as well. The modem parameter partition should reside in a fixed location and has therefore been moved to a fixed location at the start of the memory. Other partitions have been moved accordingly, but the kernel image and root file system partition locations and sizes have been kept as they were.

2010-08-30U-boot: MMC update.Martin LUNDHOLM
MMC has been updated with several improvements. Primarily MMC performance has been improved by using assembler code for low level FIFO handling. Also some MMC functionality has been added, e.g. support for DDR and reliable write. Data and command delay times were incremented, otherwise hangups and timeouts were observed. Tested on HREF+ 1.1 V21 and HREF+ 1.1 V32 (Micron PoP). Following WP depends on this change (more reliable SD card write support): ST-Ericsson ID: WP264488 Change-Id: Ic92abffe1640aa9375b8d43a6b8522ca8296a368 Reviewed-on: http://gerrit.lud.stericsson.com/gerrit/4056 Reviewed-by: Michael BRANDT <michael.brandt@stericsson.com> Tested-by: Michael BRANDT <michael.brandt@stericsson.com>

2010-08-11Replace MMC/SD driver to fit new framework.Ulf Hansson
IR265772: MMC driver does not detect SDHC cards. IR254201: Restructure MMC/SD driver for U8500 board according to the block device framework in mainline U-Boot. Changes to mmc framework: - Multi Block Read support in mmc framework. - Wrap Multi Block Write/Read to be able to adopt for large transaction. - Removed incorrect check in EXT CSD for high capacity MMC. - Corrected check for high capacity SD cards. - Set MMC buswidth to 8, prio of using 4. Known limitations/bugs in mmc framework: - High capacity MMC, will likely not get the correct density. - High speed is set, whether or not the host supports it or not. board/st/u8500/mmc_utils: IMPORTANT FOR DEVELOPERS: - Removed unessary U-Boot commands which is already supported in cmd_fat. - mmc_read_cmd_file: Read command.txt into bootcmd env from FAT FS in SD card. - write_partition_block: Writes the MBR if it is not already written. board/st/u8500/mmc_host[c.h]: - Implements the entire MMC/SD host driver for the PL180 block. - There is still room for optimization: Increase CLK-speed. Use high-speed for SD cards. Is GPIO setup correctly for both cards an eMMC. EarlyDrop support not fully tested. Dynamically turn on voltage/clocks to SD, not always. More... Note: - Increased read/write performance for eMMC, to around 5.4 MB/s for sequential read/write. Earlier measurements was 3.5 MB/s for read and 2.6 MB/s for write.

2010-01-18mmc whitespace cleanupMichael Brandt
emmc.c, mmc.c, mmc_util.c: whitespace correction to pass diff --check mmc_util.c: removed unused display_file_list(), fixed type warnings.
2010-01-07PACK3 changesMichael Brandt
applied PACK3 changes: * cpu/arm_cortexa9/start.S: reset register changed, but U-Boot reset command still does not work. * config.mk: build address changed to 0x05FC0000 * board/st/u8500/mmc.c: MBR change: descrease 4th partition size (userfs 2) from 0x00c0'0000 to 0x00b9'a000 sectors (6,442,450,944 to 6,228,541,440 bytes). * board\st\u8500\init_mmc.c: modify bootargs to set board_id to HREF or MOP. Is is an extremly ugly solution. It modifies the bootargs env variable directly (bootargs[9] = board_id;), instead of setting a additional environment variable board_id and use it in the bootargs envvar. * board/st/u8500/mmc.c: undocumented clock changes. * board/st/u8500/mmc_utils.c: new routine to switch to 4-bit interface. The switch is done in mmc_read_file(). It would make more sense to do so in mmc_init. * board/st/u8500/u8500.c: clock changes for HSI and I2C. I2C is now clocked by SOC1 PLL and runs with 24 MHz (depends on boot ROM SOC1 initialisation)
2009-11-10PACK2 changesMichael Brandt
merged PACK2 changes: mmc and i2c frequency, put the second core into wfe, default bootcmd.
