This patch introduce TF-A support for NXP's ls1043a platform. more details information of ls1043a chip and ls1043ardb board can be found at docs/plat/ls1043a.rst. Boot sequence on ls1043a is: bootrom loads bl1 firstly, then bl1 loads bl2, bl2 will load bl31, bl32 and bl33, bl31 will boot bl32(tee os) and bl33(u-boot or uefi), bl33 boot Linux kernel. Now TF-A on ls1043ardb platform has the following features in this patch: * Support boot from Nor flash. * TF-A can boot bl33 which runs in el2 of non-secure world. * TF-A boot OPTee OS. * Support PSCI Signed-off-by: Jiafei Pan <Jiafei.Pan@nxp.com> Signed-off-by: Chenyin.Ha <Chenyin.Ha@nxp.com> Signed-off-by: Chenhui Zhao <chenhui.zhao@nxp.com> Signed-off-by: jiaheng.fan <jiaheng.fan@nxp.com> Signed-off-by: Wen He <wen.he_1@nxp.com>
