| * relocation: Do not relocate NULL pointers.Joakim Tjernlund2009-10-08-24/+48
| | | | | | | | | | | | | | | | | | | | 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.

| * 85xx: Ensure BSS segment isn't linked at address 0Peter Tyser2009-10-08-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When U-Boot is relocated from flash to RAM pointers are modified accordingly. However, pointers initialzed with NULL values should not be modified so that they maintain their intended NULL value. If the BSS segment is linked at address 0 its address will not be updated as necessary during relocation. This is a temporary workaround. The end goal is to add support to U-Boot to dynamically locate the BSS at an arbitrary address at runtime. When the ability to fixup the BSS inteligently is added, this workaround can be removed and the 85xx link script can put the BSS at a fixed address at link time.

| * ppc: Enable full relocation to RAMPeter Tyser2009-10-03-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* | PPC4xx: Denali core: Fix incorrect DDR row bitsMike Nuss2009-10-07-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The SPD detection code for the Denali memory controller used on some ppc4xx processors incorrectly encodes DDR0_42. With certain memory configurations, this can cause the bootwrapper to incorrectly calculate the installed memory size, because the number of row bits is wrong. This patch fixes that encoding.

* | ppc4xx: Merge PPC4xx DDR and DDR2 ECC handlingStefan Roese2009-10-02-250/+169
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch merges the ECC handling (ECC parity byte writing) into one file (ecc.c) for all PPC4xx SDRAM controllers except for PPC440EPx/GRx. This exception is because only those PPC's use the completely different Denali SDRAM controller core. Previously we had two routines to generate/write the ECC parity bytes. With this patch we now only have one core function left. Tested on Kilauea (no ECC) and Katmai (with and without ECC).

|/ | | | | | | | | | | | | | | | | | | some LCRR bits are not documented throughout the 83xx family RMs. New board porters copying similar board configurations might omit setting e.g., DBYP since it was not documented in their SoC's RM. Prevent them bricking their board by retaining power on reset values in bit fields that the board porter doesn't explicitly configure via CONFIG_SYS_<registername>_<bitfield> assignments in the board config file. also move LCRR assignment to cpu_init_r[am] to help ensure no transactions are being executed via the local bus while CLKDIV is being modified. also start to use i/o accessors.

* mucmc52, uc101: delete ata@3a00 node, if no CF card is detectedHeiko Schocher2009-09-25-0/+20
| | | | | | | | | | | U-Boot can detect if an IDE device is present or not. If not, and this new config option is activated, U-Boot removes the ATA node from the DTS before booting Linux, so the Linux IDE driver does not probe the device and crash.

* 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/+181
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
