ppc4xx: Fix 460EX errata with CPU lockup upon high AHB traffic
This patch implements a fix provided by AMCC so that the lockup upon simultanious traffic on AHB USB OTG, USB 2.0 and SATA doesn't occur anymore: Set SDR0_AHB_CFG[A2P_INCR4] (bit 24) and clear SDR0_AHB_CFG[A2P_PROT2] (bit 25) for a new 460EX errata regarding concurrent use of AHB USB OTG, USB 2.0 host and SATA. This errata is not officially available yet. I'll update the comment to add the errata number later. Signed-off-by: Stefan Roese <sr@denx.de>
