This is some more cleanup moving to IO accessor functions. And yes, I know about the checkpatch warnings, but this is inline with the current code.

[U-Boot] [PATCH 0/2] omap3: Optimize detection of cpu revision
by Sanjeev Premi 17 Jan '10

17 Jan '10

Each call to get_cpu_rev() leads to repetitive execution of code to detect the cpu revision. This patchset ensures that mechanism to detect revision is not executed each time; instead a stored value is returned. Since, revision info is needed in s_init(), the function to identify cpu revision needs to be called twice. At the moment, it is necessary/ unavoidable.

[U-Boot] [PATCH V2] ppc4xx: Canyonlands: Fix USB host PHY reset sequence
by Dave Mitchell 14 Jan '10

14 Jan '10

Current de-assert reset is not sufficient for the USB PHY reset on some Canyonlands platforms. The patch adds an assert/de-assert sequence. This addresses a USB detection problem for devices attached prior to power-up. The delay lengths are needed for power to the PHY to stabilize.

[U-Boot] [PATCH] mpc83xx: Add NAND boot support for MPC8315E-RDB boards
by Anton Vorontsov 12 Jan '10

12 Jan '10

The core support for NAND booting is there already, so this patch is pretty straightforward. There is one trick though: top level Makefile expects nand_spl to be in nand_spl/board/$(BOARDDIR), but we can fully reuse the code from mpc8313erdb boards, and so to not duplicate the code we just symlink nand_spl/board/freescale/mpc8315erdb to mpc8313erdb.
