* sbc8548: enable access to second bank of flashPaul Gortmaker2009-09-24-7/+29
| | | | | | | | | | | | | | | | | | | The sbc8548 has a 64MB SODIMM flash module off of CS6 that previously wasn't enumerated by u-boot. There were already BR6/OR6 settings for it [used by cpu_init_f()] but there was no TLB entry and it wasn't in the list of flash banks reported to u-boot. The location of the 64MB flash is "pulled back" 8MB from a 64MB boundary, in order to allow address space for the 8MB boot flash that is at the end of 32 bit address space. This means creating two 4MB TLB entries for the 8MB chunk, and then expanding the original boot flash entry to 64MB in order to cover the 8MB boot flash and the remainder (56MB) of the user flash.

* sbc8548: get_clock_freq is not valid for this boardPaul Gortmaker2009-09-24-3/+3
| | | | | | | | | | | The get_clock_freq() comes from freescale/common/cadmus.c and is only valid for the CDS based 85xx reference platforms. It would be nice if we could read the 33 vs. 66MHz status somehow, but in the meantime, tie it to CONFIG_SYS_CLK_FREQ like all the other non-CDS boards do.

* sbc8548: delete unused MPC8548CDS info carried over from portPaul Gortmaker2009-09-24-66/+6
| | | | | | | | | | | | | | | | | | There are a couple defines and PCI bridge quirks related to the PCI backplane of the MPC8548CDS that have no meaning in the context of the port to the sbc8548 board, so delete them. Also, the form factor of the sbc8548 is a standalone board with a single PCI-X and a single PCI-e slot. That pretty much guarantees that it will never be a PCI agent itself, so the host/agent and root complex/end node distinctions have been removed. Similarly, since there is no physical connector mapping to PCI2, so all references of PCI2 in the board support files have been removed as well.

* ppc/85xx: 32bit DDR changes for P1020/P1011Poonam Aggrwal2009-09-24-5/+24
| | | | | | | | | | | | | The P1020/P1011 SOCs support max 32bit DDR width as opposed to P2020/P2010 where max DDR data width supported is 64bit. As a next step the DDR data width initialization would be made more dynamic with more flexibility from the board perspective and user choice. Going forward we would also remove the hardcodings for platforms with onboard memories and try to use the FSL SPD code for DDR initialization.

* sbc8548: replace README with completely new documentPaul Gortmaker2009-09-24-23/+173
| | | | | | | | | | | | | The previous README.sbc8548 was pretty much content-free. Replace it with something that actually gives the end user some relevant hardware details, and also lists the u-boot configuration choices. Also in the cosmetic department, fix the bogus line in the Makefile that was carried over from the SBC8560 Makefile, and the typo in the sbc8548.c copyright.

| | | | | | | | | | | | | | | | | | | | | For some reason the CLKDIV field varies between SoC in how it interprets the bit values. All 83xx and early (e500v1) PQ3 devices support: clk/2: CLKDIV = 2 clk/4: CLKDIV = 4 clk/8: CLKDIV = 8 Newer PQ3 (e500v2) and MPC86xx support: clk/4: CLKDIV = 2 clk/8: CLKDIV = 4 clk/16: CLKDIV = 8 Ensure that the MPC86xx and MPC85xx still get the same behavior and make the defines reflect their logical view (not the value of the field).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All 4xx variants had their own, mostly identical get_OPB_freq() function. Some variants even only had the OPB frequency calculated in this routine and not supplied the sys_info.freqOPB variable correctly (e.g. 405EZ). This resulted in incorrect OPB values passed via the FDT to Linux.

* | ppc/85xx: add boot from NAND/eSDHC/eSPI supportMingkai Hu2009-09-15-1/+183

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>
