2016-05-17armv8/ls1043: Add workaround for DDR erratum A-008850Shengzhou Liu
Barrier transactions from CCI400 need to be disabled till the DDR is configured, otherwise it may lead to system hang. The patch adds workaround to fix the erratum. Signed-off-by: Shengzhou Liu <Shengzhou.Liu@nxp.com> Reviewed-by: York Sun <york.sun@nxp.com>

2015-12-15armv8: fsl-layerscape: Make DDR non secure in MMU tablesYork Sun
DDR has been set as secure in MMU tables. Non-secure master such as SDHC DMA cannot access data correctly. Mixing secure and non- secure MMU entries requirs the MMU tables themselves in secure memory. This patch moves MMU tables into a secure DDR area. Early MMU tables are changed to set DDR as non-secure. A new table is added into final MMU tables so secure memory can have 2MB granuality. gd->secure_ram tracks the location of this secure memory. For ARMv8 SoCs, the RAM base is not zero and RAM is divided into several banks. gd->secure_ram needs to be maintained before using. This maintenance is board-specific, depending on the SoC and memory bank of the secure memory falls into. Signed-off-by: York Sun <yorksun@freescale.com>
