* 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.

* ppc/85xx: Clean up use of LAWAR definesKumar Gala2009-09-24-31/+26
| | | | | | | | | On 85xx platforms we shouldn't be using any LAWAR_* defines but using the LAW_* ones provided by fsl-law.h. Rename any such uses and limit the LAWAR_ to the 83xx platform as the only user so we will get compile errors in the future. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* ppc/85xx: Fix LCRR_CLKDIV definesKumar Gala2009-09-24-3/+11
| | | | | | | | | | | | | | | | | | | | | 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).

| * | ppc4xx: Consolidate get_OPB_freq()Stefan Roese2009-09-17-75/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. This patch now removes all those copies and only uses one function for all 4xx variants (except for IOP480 which doesn't have an OPB). Signed-off-by: Stefan Roese <sr@denx.de>

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

So create two netcat processes - one to only listen (and put it into a loop), and one to do the sending. Once the user quits the transmitting netcat, the listening one will be killed automatically.
