This patch makes a few small cleanups to the cuboot code. - It removes the double layered selection of images, via cuboot-plat-y, instead having the cuboot platforms directly select a suitable image-y (this changes the name of the final cuboot image from plain cuImage to cuImage.<platform>). - Factors out some code in the wrapper that's potentially useful to platforms other than uboot.

The uppermost part of memory is where u-boot puts the stack, so don't include that in the heap. It's not currently causing problems, as the current code allocates from the bottom of the heap, but this will keep things from potentially breaking if a future implementation were to allocate from the top.

This fixes a few bugs in how dt_xlate_reg() handles address arrays: 1. copy_val() was copying into the wrong end of the array, resulting in random stack garbage at the other end. 2. dt_xlate_reg() was getting the result from the wrong end of the array. 3. add_reg() and sub_reg() were treating the arrays as little-endian rather than big-endian. 4. add_reg() only returned an error on a carry out of the entire array, rather than out of the naddr portion. 5. The requested reg resource was checked to see if it exceeded the size of the reg property, but not to see if it exceeded the size of the buffer.

Commit 79c85419 introduced code to move the initrd if it was in a place where it would get overwritten by the kernel image. Unfortunately this exposed the fact that the code that checks whether the values passed in r3 and r4 are intended to indicate the start address and size of an initrd image was not as thorough as the kernel's checks. The symptom is that on OF-based platforms, the bootwrapper can cause an exception which causes the system to drop back into OF. Previously it didn't matter so much if the code incorrectly thought that there was an initrd, since the values for start and size were just passed through to the kernel. Now the bootwrapper needs to apply the same checks as the kernel since it is now using the initrd data itself (in the process of copying it if necessary). This adds the code to do that.

This cleans up how the zImage code manipulates the kernel command line. Notable improvements from the old handling: - Command line manipulation is consolidated into a new prep_cmdline() function, rather than being scattered across start() and some helper functions - Less stack space use: we use just a single global command line buffer, which can be initialized by an external tool as before, we no longer need another command line sized buffer on the stack. - Easier to support platforms whose firmware passes a commandline, but not a device tree. Platform code can now point new loader_info fields to the firmware's command line, rather than having to do early manipulation of the /chosen bootargs property which may then be rewritten again by the core.

This patch adds a library of useful device tree manipulation functions to the zImage library, for use by platform code. These functions are based on the hooks already in dt_ops, so they're not dependent on a particular device tree implementation. This patch also slightly streamlines the code in main.c using these new functions. This is a consolidation of my work in this area with Scott Wood's patches to a very similar end.

This patch adds a reg.h to the zImage code, with common definitions for accessing system registers. For now, this includes functions for retrieving the PVR and the stack pointer.

Before the plethora of platforms gets any worse, establish a common rule to invoke the wrapper for any platform. Add arguments to the rule for initrd, dts, dtb, etc. Show example usage with initrd. Create default rules for zImage, and zImage.initrd. initrd targets depend on the ramdisk file. Don't consider targets for zImage.initrd that are targets for zImage. This means uImage is no longer considered a target for zImage.initrd. Signed-off-by: NMilton Miller <miltonm@bga.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>
