powerpc/p4080: Add support for secure boot flow
Pre u-boot Flow: 1. User loads the u-boot image in flash 2. PBL/Configuration word is used to create LAW for Flash at 0xc0000000 (Please note that ISBC expects all these addresses, images to be validated, entry point etc within 0 - 3.5G range) 3. ISBC validates the u-boot image, and passes control to u-boot at 0xcffffffc. Changes in u-boot: 1. Temporarily map CONFIG_SYS_MONITOR_BASE to the 1M CONFIG_SYS_PBI_FLASH_WINDOW in AS=1. (The CONFIG_SYS_PBI_FLASH_WINDOW is the address map for the flash created by PBL/configuration word within 0 - 3.5G memory range. The u-boot image at this address has been validated by ISBC code) 2. Remove TLB entries for 0 - 3.5G created by ISBC code 3. Remove the LAW entry for the CONFIG_SYS_PBI_FLASH_WINDOW created by PBL/configuration word after switch to AS = 1 Signed-off-by: Ruchika Gupta <ruchika.gupta@freescale.com> Signed-off-by: Kuldip Giroh <kuldip.giroh@freescale.com> Acked-by: Wood Scott-B07421 <B07421@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
