2009-11-04Revert "ppc/85xx/pci: fsl_pci_init: pcie agent mode support"Kumar Gala
This reverts commit 70ed869ea5f6b1d13d7b140c83ec0dcd8a127ddc. There isn't any need to modify the API for fsl_pci_init_port to pass the status of host/agent(end-point) status. We can determine that internally to fsl_pci_init_port. Revert the patch that makes the API change. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2009-09-30sbc8548: reclaim wasted sector in boot flashPaul Gortmaker
By nature of being based off the MPC8548CDS board, this board inherited an ENV_SIZE setting of 256k. But since it has a smaller flash device (8MB soldered on), it has a native sector size of 128k, and hence the ENV_SIZE was causing 2 sectors to be used for the environment. By removing the unused sector, we can push TEXT_BASE up closer to the end of address space and reclaim that sector for any other application. This also fixes the mismatch between TEXT_BASE and MONITOR_LEN reported by Kumar earlier. Since this board also supports the ability to boot off the 64MB SODIMM flash, this change is forward looking with that in mind; i.e. the settings for MONITOR_LEN and ENV_SIZE will work when the 512k sectors of the SODIMM flash are used for alternate boot in the future.

2009-09-24sbc8548: update PCI/PCI-e support codePaul Gortmaker
The PCI/PCI-e support for the sbc8548 was based on an earlier version of what the MPC8548CDS board was using, and in its current state it won't even compile. This re-syncs it to match the latest codebase and makes use of the new shared PCI functions to reduce board duplication. It borrows from the MPC8568MDS, in that it pulls the PCI-e I/O back to 0xe280_0000 (where PCI2 would be on MPC8548CDS), and similarly it coalesces the PCI and PCI-e mem into one single TLB. Both PCI-x and PCI-e have been tested with intel e1000 cards under linux (with an accompanying dts change in place) Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-09-24sbc8548: correct local bus SDRAM size from 64M to 128MPaul Gortmaker
The size of the LB SDRAM on this board is 128MB, spanning CS3 and CS4. It was previously only being configured for 64MB on CS3, since that was what the original codebase of the MPC8548CDS had. In addition to setting up BR4/OR4, this also adds the TLB entry for the second half of the SDRAM.

2009-09-24sbc8548: enable access to second bank of flashPaul Gortmaker
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.

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.

2009-09-24sbc8548: delete unused MPC8548CDS info carried over from portPaul Gortmaker
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.

2009-03-20Fix all linker script to handle all rodata sectionsTrent Piepho
A recent gcc added a new unaligned rodata section called '.rodata.str1.1', which needs to be added the the linker script. Instead of just adding this one section, we use a wildcard ".rodata*" to get all rodata linker section gcc has now and might add in the future. However, '*(.rodata*)' by itself will result in sub-optimal section ordering. The sections will be sorted by object file, which causes extra padding between the unaligned rodata.str.1.1 of one object file and the aligned rodata of the next object file. This is easy to fix by using the SORT_BY_ALIGNMENT command. This patch has not be tested one most of the boards modified. Some boards have a linker script that looks something like this: *(.text) . = ALIGN(16); *(.rodata) *(.rodata.str1.4) *(.eh_frame) I change this to: *(.text) . = ALIGN(16); *(.eh_frame) *(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*))) This means the start of rodata will no longer be 16 bytes aligned. However, the boundary between text and rodata/eh_frame is still aligned to 16 bytes, which is what I think the real purpose of the ALIGN call is. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>

2008-06-12Change initdram() return type to phys_size_tBecky Bruce
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.

2008-01-12Fix linker scripts: add NOLOAD atribute to .bss/.sbss sectionsWolfgang Denk
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>
