2011-11-17Increase FSMC data-phase timing for ethernet controller SRAM transfersGregory Hermant
The ethernet controller reportedly suffers data corruption of transfers from SRAM through the Flexible Smart Memory Controller on some PDK boards. Increasing the data-phase timing for the transfers fixes these problems.

2011-01-18U8500: Add support for HREFP 2.0 V60 and laterMichael Brandt
The HREFP 2.0 V60 has no GPIO expander, therefore some GPIO lines were moved around. The preferred approach was to first check if there is a machid in the environment. And if not try to program the GPIOE. If that fails, assume it is a V60 or newer. But for the splash screen, we need to know very early on which HW version we are running. At that time no environment is available, therefore it is unavoidable to do the I2C access (10 ms timeout), if both HW versions shall be supported in one binary. CAUTION: you need also a Linux kernel which supports MACH_TYPE_HREFV60. Older U8500 kernels will not even issue a start-up message.

2010-12-08db8500: New GPIO driver and config, from Linux kernelJoakim Axelsson
Copied the GPIO configurator written for the Linux kernel. The Nomadik db8500 GPIO driver. Purpose is to be able to just cut-n-paste the GPIO config from Linux to U-boot. Also at the same time remove the obsolete and old gpio_alt_funcenable/disable methods. Now all is configured using a table in u8500.c. Now drivers doesn't have to worry about setting up the GPIO pins. Actually no driver today uses GPIO pins directly, only via hardware blocks within db8500. Functions are still added to be able to interact directly with a GPIO pin. This also cleaned up a lot of driver by not having to bit manipulate GPIO registers them self. The new driver is called db8500_gpio and placed in driver/gpio/. Functions are in include/db8500_gpio.h: void db8500_gpio_set_pull(unsigned gpio, enum db8500_gpio_pull pull); void db8500_gpio_make_input(unsigned gpio); int db8500_gpio_get_input(unsigned gpio); void db8500_gpio_make_output(unsigned gpio, int val); void db8500_gpio_set_output(unsigned gpio, int val); And for the configurator in include/db8500_pincfg.h: void db8500_gpio_config_pins(pin_cfg_t *cfgs, size_t num); All in all the final binary size has decreased. This is only done for db8500 nomadik GPIO. The code for gpio expanders has not been touched. All references to Nomadik has been removed in this driver. Only db8500 is left.

2010-07-07memory bootargs changeMichael Brandt
Related to ER 265783 "Existing SI memory map no more compatible for MM" and ER 260608 "VC: Black incoming call screen". The Linux kernel and graphics memory parameters have changed. Furthermore there are different layouts for 256 MB and 512 MB SDRAM resp. With this change U-Boot detects dynamically the memory size by making some fixed assumptions about the memory chip and controller and by reading the number of actually used rows and columns. It then sets the environment variable memargs to add either memargs256 or memargs512 to "bootargs". "memargs256" and "memargs512" are stored in the U-Boot environment area. The default values are set in include/configs/u5000.h Also the default uImage copy size was increased from 2 MiB to 3 MiB, since the released uImage size is close to 2 MiB and some developers uImage is already above. Tested with HREF ED (256 MB) (LBP only), HREF 1.0 V20 OM (256 MB) and HREF+ 1.1 V31 (512 MB). Erase the U-Boot environment first, if you want the new settings.

2010-05-19HREF V1 updatesMichael Brandt
This patch is part of WP254081 which depends on WP252006. * Fixed I2C, use real timeouts instead of counter * Undefined CONFIG_BOOTTIME, since it as to be changed to new timer.c * Merged V1 patches from Bangalore The patches were merged manually, because of the differences of the U-Boot baseline (Bangalore U-Boot 1.3.1, Lund 2009.11). The original patches were created by Rabin Vincent <rabin.vincent@stericsson.com>. and were applied originally to Branches: blr_lsp, remotes/origin/blr_lsp Follows: qpppaaa_20100210_094651 0001-u8500-gpio-add-I2C0-altfun.patch 0002-u8500-use-correct-v1-macros.patch 0003-emmc-clean-up-paritioning.patch 0004-u8500-remove-incorrect-ram-settings.patch 0005-u8500-gpio-remove-unnecessary-ifdefs.patch 0006-u8500-add-ED-v1-detection-and-handle-eMMC-diff.patch 0008-u8500-mmc-don-t-disable-altfuns.patch 0009-u8500-gpio-remove-unused-defined.patch 0010-u8500-mmc-add-barrier-for-while-loop.patch 0011-u8500-mmc-handle-non-block-addressed-cards.patch 0012-u8500-mmc-remove-unused-gpio-settings-on-v1.patch 0013-u8500-emmc-build-fix.patch 0014-u8500-handle-v1-gpios-and-clocks.patch 0015-mmc-build-fix-for-block-addressing.patch 0016-u8500-add-clocks-and-hardware-files.patch 0017-u8500-enable-PRCUM-timers-reg-for-ED.patch 0018-u8500-handle-MTU-for-v1-ED.patch 0019-u8500-emmc-remove-unnecessary-GPIO-settings.patch 0020-u8500-remove-dead-code.patch 0021-u8500-add-working-MTU-timer.patch 0022-pl011-empty-rx-fifo-if-necessary.patch 0023-u8500-gpio-fix-cont-handling-in-altfunc.patch 0024-u8500-reduce-bootdelay-to-1-and-enable-zero-check.patch 0025-u8500-disable-forcing-of-verify-but-set-n-by-default.patch 0029-u8500-fix-some-gpio-settings.patch 0030-emmc-make-v1-paritioning-differences-explicit.patch Signed-off-by: Michael Brandt <Michael.Brandt@stericsson.com> Change-Id: I1106702e393c34f630e71f071e06c3952b0d3a1a Reviewed-on: http://gerrit.lud.stericsson.com/gerrit/182 Reviewed-by: Michael BRANDT <michael.brandt@stericsson.com> Tested-by: Jonas ABERG <jonas.aberg@stericsson.com> Reviewed-by: Jonas ABERG <jonas.aberg@stericsson.com>
2010-05-19General I2C refactoring and environment settings cleanupMichael Brandt
These are the patches for WP252006. There will be a follow-up patched for WP254081. Environment settings * board_id bootargs parameter from board_id environment var set in board_late_init(). * decreased bootdelay to 1 second * added check for keypress on bootdelay==0 * removed preboot command and introduced "run cmdfile" instead * changed rootfstype from ext2 to ext3 General I2C refactoring * include/configs/u8500.h: Enabled i2c command line commands. Changed environment settings to use board_id as set in board_late_init(). Added I2C address and configuration defines. * board/st/u8500/Makefile: Replaced i2c.o with u8500_i2c.o. * board/st/u8500/gpio.c, gpio.h: Added I2C busses to altfunc_table. * board/st/u8500/init_mmc.c: removed config_extended_gpio() and therefore I2C references. GPIOE settings are now in board_late_init(). * board/st/u8500/u8500.c: Removed I2C/SD gpio settings from addr,value array. board_late_init(): Determine and set board_id environment variable 0: mop500, 1: href500 Above boards have different GPIO expander chips which we can distinguish by the chip id (1 and 3). The board_id environment variable is needed for the Linux bootargs.

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)

clkinfo command shows current PLL and clock settings. clkmaja changes certain clocks to be more U5500 (Maja) alike. With make u8500_SRAM_config a U-Boot suitable to run from SRAM can be compiled. Signed-off-by: Michael Brandt <Michael.Brandt@stericsson.com>
