* omap2/3/4: Disable CONFIG_FB_OMAP in omap3_defconfigTony Lindgren2010-05-051-9/+1Star
| | | | | | | | | | | | | Looks like CONFIG_FB_OMAP prevents somehow mounting root on MMC at least on zoom3 for multi-omap. Disable CONFIG_FB until the omap FB code is fixed. This allows booting omap3_defconfig on various omaps. Tested on 2420-n8x0, 3430-n900, 3630-zoom3 and 4430-blaze. Note that n8x0 still has issues with starting user space because of TLS and VFP.

* omap2/3/4: Make omap3_defconfig usable on Nokia boardsTony Lindgren2010-05-041-2/+2
| | | | | | | | | | | | | | | | | The bootloader on Nokia boards does not support updating the kernel cmdline. For the other boards, the bootloader provided cmdline will be used instead. To mount root on n8x0, compile in also the MMC_OMAP. It seems that the best way to mount root with the new kernels on Nokia boards is to mount root on mmcblk0p2. Note that n8x0 current has several issues booting with omap3_defconfig: The bootloader has a 2MB limit for loading kernels, so you may want to use kexec. Also ARMv6 does not currently work with ARMv7 for VFP and TLS. Signed-off-by: Tony Lindgren <tony@atomide.com>

| | | | | | | | | | | | We cannot use the omap34xx_sram_init(). It needs to be implemented for omap4.

* omap2/3: Fix DEBUG_LL for omap zoom2/3Tony Lindgren2010-05-046-8/+17
| | | | | | | | | | | | | | | | | Zoom2 and 3 have UARTs only on the external debug board. GPMC needs to be mapped early to use it for DEBUG_LL. Additionally, 0xfb000000 overlaps with other areas, so use 0xfa400000 for the virtual address instead. Note that with the pending serial.c patches you need to set console=ttyS0,115200n8 as it will be the only UART mapped. To use DEBUG_LL, you need to pass also earlyprintk in cmdline.

* omap: Use a memory address for storing the debug port info instead of UART1 ↵Tony Lindgren2010-05-044-47/+43Star
| | | | | | | | | | | | | | | | | | | | | | scratchpad This removes the dependency to the UART1 being available for storing the debug configuration in uncompress.h. This will simplify the DEBUG_LL UART configuration for boards that may not have UART1, or have an external UART as it requires only one mapping for DEBUG_LL. The patch has a few limitations. Basically now we're assuming that the kernel uncompress code won't overlap with OMAP_UART_INFO. We also assume the printascii is called at least once before paging_init in order for addruart to have a chance to read the UART setup from OMAP_UART_INFO. As suggested by Cyril Chemparathy <cyril@ti.com>, Vikram Pandita <vikram.pandita@ti.com> and Kevin Hilman <khilman@deeprootsystems.com>. Based on an earlier patch posted for Davinci by Cyril Chemparathy <cyril@ti.com>. Signed-off-by: Tony Lindgren <tony@atomide.com>

Unfortunately the old method now caps the topology to work around issues with legacy operating systems. For Linux to get the correct topology we need to use the new form 1 affinity information. We set the form 1 field in the client architecture, and if we see "1" in the ibm,associativity-form property firmware supports form 1 affinity and we should look at the first field in the ibm,associativity-reference-points array. If not we use the second field as we always have. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

Linux has been computing Address Spaces as [_MIN to _MIN + _LEN - 1]. Based on the tests in the bug reports below, Windows apparently uses [_MIN to _MAX]. Per spec (ACPI 4.0, Table 6-40), for _CRS fixed-size, fixed location descriptors, "_LEN must be (_MAX - _MIN + 1)", and when that's true, it doesn't matter which way we compute the end. But of course, there are BIOSes that don't follow this rule, and we're better off if Linux handles those exceptions the same way as Windows. This patch makes Linux use [_MIN to _MAX], as Windows seems to do. This effectively reverts d558b483d5 and 03db42adfe and replaces them with simpler code. https://bugzilla.kernel.org/show_bug.cgi?id=14337 (round) https://bugzilla.kernel.org/show_bug.cgi?id=15480 (truncate) Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
| * | | x86/PCI: never allocate PCI MMIO resources below BIOS_ENDBjorn Helgaas2010-04-261-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we move a PCI device or assign resources to a device not configured by the BIOS, we want to avoid the BIOS region below 1MB. Note that if the BIOS places devices below 1MB, we leave them there.
