2007-08-22[POWERPC] bootwrapper: Add PowerQUICC II (82xx with CPM) cuboot supportScott Wood
This allows booting on legacy, non-device-tree aware versions of U-boot. It also fixes up the hardware to match the PCI and chipselect information in the device tree, as u-boot is inconsistent in setting these up correctly (or at all).

2007-08-22[POWERPC] bootwrapper: Add CPM serial driverScott Wood
This serial port is used on all 8xx, many 82xx, and some 85xx chips. The driver requires that the port has already been set up by the firmware and/or platform code.

2007-08-22[POWERPC] bootwrapper: serial_console_init() fixesScott Wood
1. Search the entire compatible list for serial devices. The serial code previously did a simple strcmp on the compatible node; this fails when the match string is not the first compatible listed. Use dt_is_compatible() instead. 2. Don't call serial_edit_cmdline if getc isn't defined.

2007-08-22[POWERPC] bootwrapper: Add TARGET_HAS_ETHn tests to ppcboot.hScott Wood
U-boots more recent than when ppcboot.h was forked allow the board config file to enable additional ethernet ports explicitly, rather than using a hardcoded list of targets. This allows bootwrapper platform files to do the same. Fortunately, nothing after the ethernet addresses is of interest to cuboot platforms, so the inevitable mismatches won't be too catastrophic.

2007-08-22[POWERPC] bootwrapper: dt_xlate_range() bugfixesScott Wood
1. The check whether ranges fits in the buffer was using elements rather than bytes. 2. Empty ranges were not properly treated as transparent, and missing ranges were treated as transparent. 3. The loop terminated when translating from the root rather than to. Once bug #2 was fixed, it failed due to a missing ranges in the root node. 4. In decoding the ranges property, the #size-cells used was that of the parent, not the child.

2007-08-17[POWERPC] Fixes to allow use of Ebony's flash chips through physmap_ofDavid Gibson
This patch contains a handful of small fixes to allow the Ebony's flash to be exposed as MTD devices via the physmap_of driver. Specifically it: - Makes a small addition to the device tree and zImage wrapper to record the correct address for the flash in the device tree based on the board switches as reported via an FPGA register. - Prohibits building the old hard-coded "Ebony" flash map on arch/powerpc kernels, in favour of using physmap_of's device tree based approach. - Enables MTD and physmap_of in the Ebony defconfig.

2007-07-10[POWERPC] PS3: Bootwrapper support.Geoff Levand
Add support to build the PS3 flash rom image and remove some unneeded lmb calls. The PS3's lv1 loader supports loading gzipped binary images from flash rom to addr zero. The loader enters the image at addr 0x100. In this implementation a bootwrapper overlay is use to arrange for the kernel to be loaded to addr zero and to have a suitable bootwrapper entry at 0x100. To construct the rom image, 0x100 bytes from offset 0x100 in the kernel is copied to the bootwrapper symbol __system_reset_kernel. The 0x100 bytes at the bootwrapper symbol __system_reset_overlay is then copied to offset 0x100. At runtime the bootwrapper program copies the 0x100 bytes at __system_reset_kernel to addr 0x100. zImage.ps3 is a wrapped image that contains a flat device tree, an lv1 compatible entry point, and an optional initrd. otheros.bld is the gzip compresed rom image built from zImage.ps3. otheros.bld is suitable for programming into the PS3 boot flash memory.

platforms Commit 2e6016133755eb3cc44e8efab92573d23ed75888 split up arch/powerpc/boot/of.c so that some OF functions can be used on platforms that don't want to use the overall OF platform boot code. This is useful on things like PReP which can have an OF implementation which is useful for debugging output, but inadequate for booting. However, that commit didn't export quite enough things to make a usable OF console on a non-OF system. In particular, the device tree manipulation performed to initialize the OF console code must explicitly use the OF device tree, rather than the flattened device tree, even if the system is otherwise booting using a flattened device tree.
