* fsl: improve the PIXIS code and fix a few bugsTimur Tabi2010-04-07-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Refactor and document the Freescale PIXIS code, used on most 85xx and 86xx boards. This makes the code easier to read and more flexible. Delete pixis.h, because none of the exported functions were actually being used by any other file. Make all of the functions in pixis.c 'static'. Remove "#include pixis.h" from every file that has it. Remove some unnecessary #includes. Make 'pixis_base' into a macro, so that we don't need to define it in every function. Add "while(1);" loops at the end of functions that reset the board, so that execution doesn't continue while the reset is in progress. Replace in_8/out_8 calls with clrbits_8, setbits_8, or clrsetbits_8, where appropriate. Replace ulong/uint with their spelled-out equivalents. Remove unnecessary typecasts, changing the types of some variables if necessary. Add CONFIG_SYS_PIXIS_VCFGEN0_ENABLE and CONFIG_SYS_PIXIS_VBOOT_ENABLE to make it easier for specific boards to support variations in the PIXIS registers sets. No current boards appears to need this feature. Fix the definition of CONFIG_SYS_PIXIS_VBOOT_MASK for the MPC8610 HPCD. Apparently, "pixis_reset altbank" has never worked on this board.

* ppc: Use r12 instead of r14 as GOT pointer.Joakim Tjernlund2010-01-26-5/+6
| | | | | | | | r14 is not supposed to be clobbered by functions. Switch to r12 and call GET_GOT when needed. This will allow u-boot to loose the -ffixed-r14 gcc option. Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se>
* ppc: Loose GOT access in IRQJoakim Tjernlund2010-01-26-32/+3
| | | | | | | | Using the GOT in IRQ handlers requires r14 to be -ffixed-r14. Avoid this by relocatate transfer_to_handler too. This will allow to free up r14 later on. Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se>
* mpc512x: Add display of reset status registerDetlev Zundel2010-01-24-2/+3
| | | | | | | | Content of the RSR is put into gd early so we can output it together with the CPU info. The clearing of gd in board_init_f is redundant for this architecture as it is done in cpu_init_f so we remove it. Signed-off-by: Detlev Zundel <dzu@denx.de>

| * relocation: Do not relocate NULL pointers.Joakim Tjernlund2009-10-08-2/+4
| | | | | | | | | | | | | | | | | | | | NULL is an absolute value and should not be relocated. After this correction code like: void weak_fun(void) __attribute__((weak)); printf("weak_fun:%p\n", weak_fun); will still print null after relocation.

| | | | | | | | | | | | | | | | | | | | | | | | | | The following changes allow U-Boot to fully relocate from flash to RAM: - Remove linker scripts' .fixup sections from the .text section - Add -mrelocatable to PLATFORM_RELFLAGS for all boards - Define CONFIG_RELOC_FIXUP_WORKS for all boards Previously, U-Boot would partially relocate, but statically initialized pointers needed to be manually relocated.

* | mpc512x: fix fixed_sdram() init code.Wolfgang Denk2009-10-08-14/+19
|/ | | | | | | | | | Commit 054197ba and later fixes used an array to initialize some of the MDDRC parameters; however, the use of an array turned out to be a bad idea as it was not possible to correlate structure entries to array indices in readable and reliable way. Now we use a struct instead, which makes this self-explanatory. Signed-off-by: Wolfgang Denk <wd@denx.de>
* mpc512x: Streamlined fixed_sdram() init sequence.Martha M Stan2009-09-25-35/+69
| | | | | | | | | | | | | | | | | | | Signed-off-by: Martha M Stan <mmarx@silicontkx.com> Minor cleanup: Re-ordered default_mddrc_config[] to have matching indices. This allows to use the same index "N" for source and target fields; before, we had code like this out_be32(&im->mddrc.ddr_time_config2, mddrc_config[3]); which always looked like a copy & paste error because 2 != 3. Also, use NULL when meaning a null pointer. Signed-off-by: Wolfgang Denk <wd@denx.de>

* stdio/device: rework function naming conventionJean-Christophe PLAGNIOL-VILLARD2009-07-18-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far the console API uses the following naming convention: ======Extract====== typedef struct device_t; int device_register (device_t * dev); int devices_init (void); int device_deregister(char *devname); struct list_head* device_get_list(void); device_t* device_get_by_name(char* name); device_t* device_clone(device_t *dev); ======= which is too generic and confusing. Instead of using device_XX and device_t we change this into stdio_XX and stdio_dev This will also allow to add later a generic device mechanism in order to have support for multiple devices and driver instances.

* MPC512x: factor out common codeWolfgang Denk2009-07-14-1/+122
| | | | | | | | | | | | | | Now that we have 3 boards for the MPC512x it turns out that they all use the very same fixed_sdram() code. This patch factors out this common code into cpu/mpc512x/fixed_sdram.c and adds a new header file, include/asm-ppc/mpc512x.h, with some macros, inline functions and prototype definitions specific to MPC512x systems.

* mpc512x: Use serial_setbrg() in serial_init() to not duplicate the codeStefan Roese2009-06-12-21/+15
| | | | | | | | This patch removes the duplicated code for baudrate generator configuration in the PSC serial_init() implementation by calling serial_setbrg() instead of duplicating the code. Signed-off-by: Stefan Roese <sr@denx.de>
* mpc512x: Fix PSC divisor calculation for baudrate settingStefan Roese2009-06-12-1/+1
| | | | | | | The wrong input frequency was used in serial_setbrg(). This patch fixes this by using ips_clk as input frequency for the PSC baudrate generator. Signed-off-by: Stefan Roese <sr@denx.de>
* MPC512x: remove include/mpc512x.hWolfgang Denk2009-06-12-6/+19
| | | | | | | | | | | | | | | | | | | | Move needed definitions (register descriptions etc.) from include/mpc512x.h into include/asm-ppc/immap_512x.h. Instead of using a #define'd register offset, use a function that provides the PATA controller's base address. All the rest of include/mpc512x.h are register offset definitions which can be eliminated by proper use of C structures. There are only a few register offsets remaining that are needed in cpu/mpc512x/start.S; for these we provide cpu/mpc512x/asm-offsets.h which is intended as a temporary workaround only. In a later patch this file will be removed, too, and then auto-generated from the respective C structs. Signed-off-by: Wolfgang Denk <wd@denx.de> Cc: John Rigby <jcrigby@gmail.com>

* General help message cleanupWolfgang Denk2009-06-12-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* i2c: Create common default i2c_[set|get]_bus_speed() functionsPeter Tyser2009-06-12-14/+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.

* mpc5121: squash some fdt fixup errorsJohn Rigby2008-08-05-15/+62
| | | | | | | | | | | | | | | | | | | | | | | On ADS5121 when booting linux the following errors are seen: Unable to update property /soc5121@80000000:bus-frequency, err=FDT_ERR_NOTFOUND Unable to update property /soc5121@80000000/ethernet@2800:local-mac-address, err=FDT_ERR_NOTFOUND Unable to update property /soc5121@80000000/ethernet@2800:address, err=FDT_ERR_NOTFOUND This is caused by ft_cpu_setup trying to deal with both old and new soc node naming. This patch fixes this by being smarter about what to fixup. Also do soc node fixups by compatible instead of by path. A new board config called OF_SOC_COMPAT defined to be "fsl,mpc5121-immr" replaces the old OF_SOC node path that was defined to be "soc@80000000". Old device trees still work, but the compatiblity is conditional on CONFIG_OF_SUPPORT_OLD_DEVICE_TREES which is on by default in include/configs/ads5121.h.
