* mpc83xx: mpc8313 - handle erratum IPIC1 (TSEC IRQ number swappage)Kim Phillips2009-10-16-0/+39
| | | | | | | | | mpc8313e erratum IPIC1 swapped TSEC interrupt ID numbers on rev. 1 h/w (see AN3545). The base device tree in use has rev. 1 ID numbers, so if on Rev. 2 (and higher) h/w, we fix them up here.

* mpc83xx: retain POR values of non-configured ACR, SPCR, SCCR, and LCRR bitfieldsKim Phillips2009-09-26-107/+154
| | | | | | | | | | | | | | | | | | | 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.

* Fix all linker script to handle all rodata sectionsTrent Piepho2009-03-20-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* mpc83xx: PCI: Fix hard-coded first_busno valueAnton Vorontsov2009-02-23-1/+1
| | | | | | | | | | | | | | | | | | | | | We should use pci_last_busno() in pci_init_bus(), otherwise we'll erroneously re-use PCI0's first_busno for PCI1 hoses. NOTE: The patch is untested. All MPC83xx FSL boards I have have PCI1 in miniPCI form, for which I don't have any cards handy. But looking in cpu/mpc85xx/pci.c: ... #ifdef CONFIG_MPC85XX_PCI2 hose = &pci_hose[1]; hose->first_busno = pci_hose[0].last_busno + 1; And considering that we do the same for MPC83xx PCI-E support, I think this patch is correct.

* mpc83xx: PCIe: Don't start bus enumeration at 0Anton Vorontsov2009-02-23-3/+1
| | | | | | | | | | | | | | | | | | | Currently we assign first_busno = 0 for the first PCIe hose, but this scheme won't work if we have ordinary PCI hose already registered (its first_busno value is 0 too). The old code worked fine only because we have PCI disabled on MPC837XEMDS boards in stand-alone mode (see commit 00f7bbae92e3b13f2b3 "mpc83xx: fix PCI scan hang on the standalone MPC837xE-MDS boards"). But on MPC837XERDB boards we have PCI and PCIe, so the bug actually triggers. So, to fix the issue, we should use pci_last_busno() + 1 for the first_busno (i.e. last available busno).

* mpc83xx: Add support for MPC83xx PCI-E controllersAnton Vorontsov2009-01-21-2/+317
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for MPC83xx PCI-E controllers in Root Complex mode. The patch is based on Tony Li and Dave Liu work[1]. Though unlike the original patch, by default we don't register PCI-E buses for use in U-Boot, we only configure the controllers for future use in other OSes (Linux). This is done because we don't have enough of spare BATs to map all the PCI-E regions. To actually use PCI-E in U-Boot, users should explicitly define CONFIG_83XX_GENERIC_PCIE_REGISTER_HOSES symbol in the board file. And only then U-Boot will able to access PCI-E, but at the cost of disabled address translation.

* 83xx: PCI agent mode fixes for multi-board systemsIra Snyder2009-01-21-0/+5
| | | | | | | | | | | | | | | | | | When running a system with 2 or more MPC8349EMDS boards in PCI agent mode, the boards will lock up the PCI bus by scanning against each other. The boards lock against each other by trying to access the PCI bus before clearing their configuration lock bit. Both boards end up in a loop, sending and receiving "Target Not Ready" messages forever. When running in PCI agent mode, the scanning now takes place after the boards have cleared their configuration lock bit. Also, add a missing declaration to the mpc83xx.h header file, fixing a build warning. Signed-off-by: Ira W. Snyder <iws@ovro.caltech.edu> Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
