* armv8/ls1043: Add workaround for DDR erratum A-008850Shengzhou Liu2016-05-171-0/+2
| | | | | | | | | 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>
* armv8: fsl-layerscape: Make DDR non secure in MMU tablesYork Sun2015-12-151-0/+15
| | | | | | | | | | | | | | | | | | | 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>
