+ * The i.MX27 SoC is very specific with respect to exceptions: it
+ * does not provide RAM at the high vectors address (0xFFFF0000),
+ * thus only the low address (0x00000000) is useable; but that is
+ * in ROM. Therefore, vectors cannot be changed at all.
+ *
+ * However, these ROM-based vectors actually just perform indirect
+ * calls through pointers located in RAM at SoC-specific addresses,
+ * as follows:
+ *
+ * Offset Exception Use by ROM code
+ * 0x00000000 reset indirect branch to [0x00000014]
+ * 0x00000004 undefined instruction indirect branch to [0xfffffef0]
+ * 0x00000008 software interrupt indirect branch to [0xfffffef4]
+ * 0x0000000c prefetch abort indirect branch to [0xfffffef8]
+ * 0x00000010 data abort indirect branch to [0xfffffefc]
+ * 0x00000014 (reserved in ARMv5) vector to ROM reset: 0xc0000000
+ * 0x00000018 IRQ indirect branch to [0xffffff00]
+ * 0x0000001c FIQ indirect branch to [0xffffff04]
+ *
+ * In order to initialize exceptions on i.MX27, we must copy U-Boot's
+ * indirect (not exception!) vector table into 0xfffffef0..0xffffff04
+ * taking care not to copy vectors number 5 (reserved exception).
