* Rewrite i386 interrupt handlingGraeme Russ2009-03-20-419/+238
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rewrite interrupt handling functionality for the i386 port. Separated functionality into separate CPU and Architecture components. It appears as if the i386 interrupt handler functionality was intended to allow multiple handlers to be installed for a given interrupt. Unfortunately, this functionality was not fully implemented and also had the problem that irq_free_handler() does not allow the passing of the handler function pointer and therefore could never be used to free specific handlers that had been installed for a given IRQ. There were also various issues with array bounds not being fully tested. I had two objectives in mind for the new implementation: 1) Keep the implementation as similar as possible to existing implementations. To that end, I have used the leon2/3 implementations as the reference 2) Seperate CPU and Architecture specific elements. All specific i386 interrupt functionality is now in cpu/i386/ with the high level API and architecture specific code in lib_i386. Functionality specific to the PC/AT architecture (i.e. cascaded i8259 PICs) has been further split out into an individual file to allow for the implementation of the PIC architecture of the SC520 CPU (supports more IRQs) Signed-off-by: Graeme Russ <graeme.russ at gmail.com>

* Fix all linker script to handle all rodata sectionsTrent Piepho2009-03-20-22/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* ppc4xx: Fix bug in PCI outbound map configuration for canyonlandsAnatolij Gustschin2009-03-20-2/+4
| | | | | | | | | | | | | | PCI outbound address map configuration doesn't match the PCI memory address range covered by appropriate TLB entry configuration for canyonlands causing machine check exceptions while accessing PCI memory regions. This patch provides a fix for this issue. Kazuaki Ichinohe observed and reported this issue while testing display output with PCI ATI video card on canyonlands.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | add CONFIG_BOOTCOUNT_LIMIT feature for 8360 CPU. The bootcounter uses 8 bytes from the muram, because no other memory was found on this CPU for the bootcount feature. So we must correct the muram size in DTS before booting Linux. This feature is actual only implemented for MPC8360, because not all 83xx CPU have qe, and therefore no muram, which this feature uses.

* 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).
