* MPC512x: use I/O accessors instead of pointer accessesWolfgang Denk2009-06-12-130/+168
| | | | | | | | This commit changes the MPC512x code to use I/O accessor calls (i.e. out_*() and in_*()) instead of using deprecated pointer accesses. Signed-off-by: Wolfgang Denk <wd@denx.de> Cc: John Rigby <jcrigby@gmail.com>
* MPC512x: add more hardware description to immap_512x.hWolfgang Denk2009-06-12-3/+3

* mpc512x: Move common files to share them by several boardsWolfgang Denk2009-06-12-1/+663
| | | | | | | | | | We will soon see several new MPC521x based boards added. This patch moves files that are not board specific to a common directory so they can be shared by all such ports. It also splits off common IDE code into a new file, cpu/mpc512x/ide.c . Signed-off-by: Wolfgang Denk <wd@denx.de> Cc: John Rigby <jcrigby@gmail.com>

* General help message cleanupWolfgang Denk2009-06-12-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many of the help messages were not really helpful; for example, many commands that take no arguments would not print a correct synopsis line, but "No additional help available." which is not exactly wrong, but not helpful either. Commit ``Make "usage" messages more helpful.'' changed this partially. But it also became clear that lots of "Usage" and "Help" messages (fields "usage" and "help" in struct cmd_tbl_s respective) were actually redundant. This patch cleans this up - for example: Before: => help dtt dtt - Digital Thermometer and Thermostat Usage: dtt - Read temperature from digital thermometer and thermostat. After: => help dtt dtt - Read temperature from Digital Thermometer and Thermostat Usage: dtt Signed-off-by: Wolfgang Denk <wd@denx.de>

* davinci: add basic dm355/dm350/dm335 supportDavid Brownell2009-06-12-0/+46
| | | | | | | | | | | | | Add some basic declarations for DaVinci DM355/DM350/DM335 support, keyed on CONFIG_SOC_DM355. (DM35X isn't quite right because the DM357 is very different; while the DM355 is like a DM355 without the MPEG/JPEG coprocessor). These have different peripherals than the DM6446, and some of the peripherals are at different addresses. Notably for U-Boot, there's no EMAC, and the NAND controller address is different Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* davinci: fix dm644x bugletsDavid Brownell2009-06-12-1/+3

* davinci: split out some dm644x-specific bits from pscDavid Brownell2009-06-12-75/+123
| | | | | | | | | | | | | | Split out DaVinci DM6446-specific bits from more generic bits: - Add a CONFIG_SOC_DM644X. All current boards use DM6446 chips; DM6443 and DM6441 chips differ in available peripherals. - Move most DM644X-specific bits from psc.c to a new dm644x.c file, which is conditionally built. It provides device-specific setup. Plus minor coding style and comment updates with respect to the PSC. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* davinci: cpu-specific build uses conditional make syntaxDavid Brownell2009-06-12-3/+5
| | | | | | | | | | | Update cpu/arm926ejs/davinci/Makefile to use COBJ-y type syntax. Add the first conditional: for EMAC driver support. Not all chips have an EMAC; and boards might not use it, anyway. This doesn't touch PHY configuration; that should eventually become conditional too.

* davinci: move psc support board-->cpuDavid Brownell2009-06-12-1/+183
| | | | | | | | Move DaVinci PSC support from board/* to cpu/* where it belongs. The PSC module manages clocks and resets for all DaVinci-family SoCs, and isn't at all board-specific. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* DaVinci now respects SKIP_LOWLEVEL_INITDavid Brownell2009-06-12-1/+5
| | | | | | | | Don't needlessly include lowlevel init code; that's only really needed with boot-from NOR (not boot-from-NAND). The 2nd stage loader (UBL) handles that before it loads U-Boot. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ppc4xx: Add Sequoia RAM-booting targetStefan Roese2009-06-12-6/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds another build target for the AMCC Sequoia PPC440EPx eval board. This RAM-booting version is targeted for boards without NOR FLASH (NAND booting) which need a possibility to initially program their NAND FLASH. Using a JTAG debugger (e.g. BDI2000/3000) configured to setup the SDRAM, this debugger can load this RAM- booting image to the target address in SDRAM (in this case 0x1000000) and start it there. Then U-Boot's standard NAND commands can be used to program the NAND FLASH (e.g. "nand write ..."). Here the commands to load and start this image from the BDI2000: 440EPX>reset halt 440EPX>load 0x1000000 /tftpboot/sequoia/u-boot.bin 440EPX>go 0x1000000 Please note that this image automatically scans for an already initialized SDRAM TLB (detected by EPN=0). This TLB will not be cleared. This TLB doesn't need to be TLB #0, this RAM-booting version will detect it and preserve it. So booting via BDI2000 will work and booting with a complete different TLB init via U-Boot works as well. Signed-off-by: Stefan Roese <sr@denx.de>
* i2c: Create common default i2c_[set|get]_bus_speed() functionsPeter Tyser2009-06-12-51/+0
| | | | | | | | | | | | | New default, weak i2c_get_bus_speed() and i2c_set_bus_speed() functions replace a number of architecture-specific implementations. Also, providing default functions will allow all boards to enable CONFIG_I2C_CMD_TREE. This was previously not possible since the tree-form of the i2c command provides the ability to display and modify the i2c bus speed which requires i2c_[set|get]_bus_speed() to be present.

* fsl-ddr: Fix handling of >4G of memory when !CONFIG_PHYS_64BITKumar Gala2009-06-12-39/+41
| | | | | | | | | | | | | | | The ddr code computes most things as 64-bit quantities and had some places in the middle that it was using phy_addr_t and phys_size_t. Instead we use unsigned long long through out and only at the last stage of setting the LAWs and reporting the amount of memory to the board code do we truncate down to what we can cover via phys_size_t. This has the added benefit that the DDR controller itself is always setup the same way regardless of how much memory we have. Its only the LAW setup that limits what is visible to the system.

| | | | | | | | | | | | | The MAXSIZE field in the TLB1CFG register is 4 bits, not 8 bits. This made setup_ddr_tlbs() try to set up a TLB larger than the e500 maximum (256 MB) which made u-boot hang in board_init_f() when trying to create a new stack in RAM.

* ppc4xx: Fix problem with ECC ordering for PPC4xx NDFC platformsStefan Roese2009-05-23-2/+2
| | | | | | | | | | | | | This patch now uses the correct ECC byte order (Smart Media - SMC) to be used on the 4xx NAND FLASH driver. Without this patch we have incompatible ECC byte ordering to the Linux kernel NDFC driver. Please note that we also have to enable CONFIG_MTD_NAND_ECC_SMC in drivers/mtd/nand/nand_ecc.c for correct operation. This is done with a seperate patch.

* Blackfin: fix timer_init()/timer_reset()Graf Yang2009-05-19-2/+3
| | | | | | | | | | | | | The timer_init() function was not using the right csync instruction, nor was it doing it right after disabling the core timer. The timer_reset() function would reset the timestamp, but not the actual timer, so there was a common edge case where get_timer() return a jump of one timestamp (couple milliseconds) right after resetting. This caused many functions to improperly timeout right away. Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
