This issue wasn't addressed because the interrupts weren't enabled on any ARMv5 core, therefore the issue wasn't noticed earlier. In previous implementation, the vectoring code used by i.MX28 CPU when an exception happened was that of the SPL. With this change, the branch target when an exception happens can be reconfigured by U-Boot.

This patch adds the minimal support for OMAP5. The platform and machine specific headers and sources updated for OMAP5430. OMAP5430 is Texas Instrument's SOC based on ARM Cortex-A15 SMP architecture. It's a dual core SOC with GIC used for interrupt handling and SCU for cache coherency. Also moved some part of code from the basic platform support that can be made common for OMAP4/5. Rest is kept out seperately. The same approach is followed for clocks and emif support in the subsequent patches.

78f455c055ddf55a1a2dd6ae5e2d060ed2e5bd0e Mon Sep 17 00:00:00 2001 From: Sricharan Date: Tue, 15 Nov 2011 09:50:03 -0500 Subject: omap4/5: Add support for booting with CH. Configuration header(CH) is 512 byte header attached to an OMAP boot image that will help ROM code to initialize clocks, SDRAM etc and copy U-Boot directly into SDRAM. CH can help us in by-passing SPL and directly boot U-boot, hence it's an alternative for SPL. However, we intend to support both CH and SPL for OMAP4/5. Initialization done through CH is limited and is not equivalent to that done by SPL. So U-Boot has to distinguish between the two cases and handle them accordingly. This patch takes care of doing this.
