* ppc/85xx: add boot from NAND/eSDHC/eSPI supportMingkai Hu2009-09-15-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MPC8536E is capable of booting form NAND/eSDHC/eSPI, this patch implements these three bootup methods in a unified way - all of these use the general cpu/mpc85xx/start.S, and load the main image to L2SRAM which lets us use the SPD to initialize the SDRAM. For all three bootup methods, the bootup process can be divided into two stages: the first stage will initialize the corresponding controller, configure the L2SRAM, then copy the second stage image to L2SRAM and jump to it. The second stage image is just like the general U-Boot image to configure all the hardware and boot up to U-Boot command line. When boot from NAND, the eLBC controller will first load the first stage image to internal 4K RAM buffer because it's also stored on the NAND flash. The first stage image, also call 4K NAND loader, will initialize the L2SRAM, load the second stage image to L2SRAM and jump to it. The 4K NAND loader's code comes from the corresponding nand_spl directory, along with the code twisted by CONFIG_NAND_SPL. When boot from eSDHC/eSPI, there's no such a first stage image because the CPU ROM code does the same work. It will initialize the L2SRAM according to the config addr/word pairs on the fixed address and initialize the eSDHC/eSPI controller, then load the second stage image to L2SRAM and jump to it. The macro CONFIG_SYS_RAMBOOT is used to control the code to produce the second stage image for all different bootup methods. It's set in the board config file when one of the bootup methods above is selected. Signed-off-by: Mingkai Hu <Mingkai.hu@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* fsl: add register read-back to set_law()Timur Tabi2009-09-08-1/+2
| | | | | | | | | After programming a new LAW, we should read-back the LAWAR register so that we sync the writes. Otherwise, code that attempts to use the new LAW-mapped memory might fail right away.

* 85xx: Added P1020 Processor Support.Poonam Aggrwal2009-08-28-1/+1
| | | | | | | | | | | | | | P1020 is another member of QorIQ series of processors which falls in ULE category. It is an e500 based dual core SOC. Being a scaled down version of P2020 it has following differences: - 533MHz - 800MHz core frequency. - 256Kbyte L2 cache - Ethernet controllers with classification capabilities. Also the SOC is pin compatible with P2020 Signed-off-by: Poonam Aggrwal <poonam.aggrwal@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* OMAP3 Move twl4030 power and led functionsTom Rix2009-07-29-0/+53
| | | | | | | | | | | | | | | | | | | | | | | | Because twl4030 now has its own device files, move exiting omap3 power_init_r to a new location. power_init_r is the only function in board/omap3/common. It initializes the twl4030 power for the board and enables the led. The power part of the the function is moved to twl4030_power_init in drivers/power/twl4030.c The power compilation is conditional on the existing config variable CONFIG_TWL4030_POWER. The led part is moved to twl4030_led_init in the new file drivers/misc/twl4030_led.c The led compilation is conditional on the new config variable CONFIG_TWL4030_LED The directory board/omap3/common was removed because power_init_r was the only function in it.

* General help message cleanupWolfgang Denk2009-06-12-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* MPC85xx: Add MPC8569 CPU supportHaiying Wang2009-03-30-1/+1
| | | | | | | | | There is a workaround for MPC8569 CPU Errata, which needs to set Bit 13 of LBCR in 4K bootpage. We setup a temp TLB for eLBC controller in bootpage, then invalidate it after LBCR bit 13 is set.
