* NAND: Fix cache and memory inconsistency issueDave Liu2009-01-23-1/+10
| | | | | | | | | | | | | | | | | | We load the secondary stage u-boot image from NAND to system memory by nand_load, but we did not flush d-cache to memory, nor invalidate i-cache before we jump to RAM. When the system has cache enabled and the TLB/page attribute of system memory is cacheable, it will cause issues. - 83xx family is using the d-cache lock, so all of d-cache access is cache-inhibited. so you can't see the issue. - 85xx family is using d-cache, i-cache enable, partial cache lock. you will see the issue. This patch fixes the cache issue. Signed-off-by: Dave Liu <daveliu@freescale.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
* Align end of bss by 4 bytesSelvamuthukumar2008-11-18-1/+6
| | | | | | | | | | Most of the bss initialization loop increments 4 bytes at a time. And the loop end is checked for an 'equal' condition. Make the bss end address aligned by 4, so that the loop will end as expected. Signed-off-by: Selvamuthukumar <selva.muthukumar@e-coninfotech.com> Signed-off-by: Wolfgang Denk <wd@denx.de>
* Make Freescale local bus registers available for both 83xx and 85xx.Haiying Wang2008-10-29-2/+2
| | | | | | | | | | | | | - Rename lbus83xx_t to fsl_lbus_t and move it to asm/fsl_lbc.h so that it can be shared by both 83xx and 85xx - Remove lbus83xx_t and replace it with fsl_lbus_t in all 83xx boards files which use lbus83xx_t. - Move FMR, FIR, FCR, FPAR, LTESR from mpc83xx.h to asm/fsl_lbc.h so that 85xx can share them.

* ARM: Add support for S3C6400 based SMDK6400 boardGuennadi Liakhovetski2008-08-31-0/+207
| | | | | | | | | SMDK6400 can only boot U-Boot from NAND-flash. This patch adds a nand_spl driver for it too. The board can also boot from the NOR flash, but due to hardware limitations it can only address 64KiB on it, which is not enough for U-Boot. Based on the original sources by Samsung for U-Boot 1.1.6.

| | | | | | | | | Note that with older board revisions, NAND boot may only work after a power-on reset, and not after a warm reset.

* Change initdram() return type to phys_size_tBecky Bruce2008-06-12-3/+3
| | | | | | | | | | | | | | | | | | | This patch changes the return type of initdram() from long int to phys_size_t. This is required for a couple of reasons: long int limits the amount of dram to 2GB, and u-boot in general is moving over to phys_size_t to represent the size of physical memory. phys_size_t is defined as an unsigned long on almost all current platforms. This patch *only* changes the return type of the initdram function (in include/common.h, as well as in each board's implementation of initdram). It does not actually modify the code inside the function on any of the platforms; platforms which wish to support more than 2GB of DRAM will need to modify their initdram() function code. Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc MPC8641HPCN. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>

* ppc4xx: Change Kilauea to use the common DDR2 init functionStefan Roese2008-06-03-14/+13
| | | | | | | | | | | This patch changes the kilauea and kilauea_nand (for NAND booting) board port to not use a board specific DDR2 init routine anymore. Now the common code from cpu/ppc4xx is used. Thanks to Grant Erickson for all his basic work on this 405EX early bootup. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx/NAND_SPL: Consolidate 405 and 440 NAND booting code in start.SStefan Roese2008-06-03-6/+5
| | | | | | | | | | | | | | | | | This patch consolidates the 405 and 440 parts of the NAND booting code selected via CONFIG_NAND_SPL. Now common code is used to initialize the SDRAM by calling initdram() and to "copy/relocate" to SDRAM/OCM/etc. Only *after* running from this location, nand_boot() is called. Please note that the initsdram() call is now moved from nand_boot.c to start.S. I experienced problems with some boards like Kilauea (405EX), which don't have internal SRAM (OCM) and relocation needs to be done to SDRAM before the NAND controller can get accessed. When initdram() is called later on in nand_boot(), this can lead to problems with variables in the bss sections like nand_ecc_pos[].

* ppc4xx: Add Canyonlands NAND booting supportStefan Roese2008-03-15-0/+315
| | | | | | | | | | | | | | | 460EX doesn't support a fixed bootstrap option to boot from 512 byte page NAND devices. The only bootstrap option for NAND booting is option F for 2k page devices. So to boot from a 512 bype page device, the I2C bootstrap EEPROM needs to be programmed accordingly. This patch adds basic NAND booting support for the AMCC Canyonlands aval board and also adds support to the "bootstrap" command, to enable NAND booting I2C setting. Tested with 512 byte page NAND device (32MByte) on Canyonlands. Signed-off-by: Stefan Roese <sr@denx.de>
* Fix linker scripts: add NOLOAD atribute to .bss/.sbss sectionsWolfgang Denk2008-01-12-4/+4
| | | | | | | | | | | | | | | | | | | With recent toolchain versions, some boards would not build because or errors like this one (here for ocotea board when building with ELDK 4.2 beta): ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab] For many boards, the .bss section is big enough that it wraps around at the end of the address space (0xFFFFFFFF), so the problem will not be visible unless you use a 64 bit tool chain for development. On some boards however, changes to the code size (due to different optimizations) we bail out with section overlaps like above. The fix is to add the NOLOAD attribute to the .bss and .sbss sections, telling the linker that .bss does not consume any space in the image. Signed-off-by: Wolfgang Denk <wd@denx.de>

So it is recommended to remove the DIMM modules while using the NAND booting code with the fixed SDRAM setup!

Since the NAND-SPL boot image is limited to 4kbytes, this version only supports the onboard 64MBytes of DDR.

* [PATCH] Speed optimization of AMCC Sequoia/Rainier DDR2 setupStefan Roese2007-03-06-1/+5
| | | | | | | | | | | | | | As provided by the AMCC applications team, this patch optimizes the DDR2 setup for 166MHz bus speed. The values provided are also save to use on a "normal" 133MHz PLB bus system. Only the refresh counter setup has to be adjusted as done in this patch. For this the NAND booting version had to include the "speed.c" file from the cpu/ppc4xx directory. With this addition the NAND SPL image will just fit into the 4kbytes of program space. gcc version 4.x as provided with ELDK 4.x is needed to generate this optimized code.
