2020-05-07MA-17076 plat: imx8: Only save data section for cold rebootJi Luo
In some cases, the bl31 won't be reloaded when spl is not supported, commit 17de039 adds the save/restore data section to fix boot issues which is caused by the dirty data in data section of previous boot. However, sometimes the backup data section in dram won't be erased totally in board cold reboot, it will be restored and modify the 'correct' data section which will cause the board hang. This commit uses a global flag 'data_section_restore_flag' which is initialized as '0x1' and should be stored in data section to indicate the save/restore behavior. Test: cold/warm reboot on imx8qm/imx8qxp. Signed-off-by: Ji Luo <ji.luo@nxp.com>

2019-12-13MLK-20986 imx8: Not protect OCRAM for rev AYe Li
On iMX8 Rev A the OCRAM is used to pass over ROM info, and u-boot needs to access it. So we can't assign the OCRAM to ATF partition. This will cause boot hang. Rev A does not support SPL, so it is ok to not protect the OCRAM.

2019-12-13imx8qm/qxp: Protect the lower 96K ocram used for SPLYe Li
Because the partition reboot won't reload the first level bootloader (SPL), the SPL won't be authenticated. Users can corrupt the SPL image to break the boot trust chain in secure boot if we don't protect that OCRAM area. This patch configures the memory area from 0x0 to 0x118000 only accessed by secure partition (ATF and OPTEE). Non-secure partitions (u-boot and kernel) can't access it.

2019-12-13imx: set CPU boot entry for partition rebootAnson Huang
With SPL running on OCRAM, when linux suspend, OCRAM will lose power and if partition reboot is started from SPL, system will hang as the OCRAM data lost, so for partition reboot, the CPU boot entry can be set to be from ATF BL31 entry directly, SCFW exposes such API for this scenario.

2019-12-13imx8: postpone moving resources to non-secure partitionPeng Fan
With flash_uboot_cm4ddr in imx-mkimage, the m4 code will access ddr. However after m4 core moved to non-secure partition, the ddr memory is still in secure partition. Then m4 core will fault. So postpone moving resources including m4 core, until other resources, such as memory/pin moved to non-secure partition.

2019-12-13imx8qxp: move M4 to OS part at lastPeng Fan
With default configuration, M4 and A35 in one partition, M4 is loaded by ROM. "err = sc_rm_move_all(ipc_handle, secure_part, os_part, true, true);" M4 core will first be moved to non-secure OS part, then the resource used by M4 will be moved to non-secure OS part later. But before the resource be moved to non-secure OS part, M4 core is still running, so a non-secure M4 core access a secure resource will trigger error in M4 side. First mark M4 core as non-movable, after all other resoures moved to OS part, move M4 to OS part. No need to check whether M4 is created a new partition by SCFW, if a partition already created, the call to mark M4 as non-removable will fail, because it M4 is in its own partition.

2019-01-29imx: power optimization for i.mx8qxAnson Huang
Current implementation of i.MX8QX power management related features does NOT optimize power number, all system resources like CCI, DDR, and A cluster etc. are kept in STBY mode (powered ON) when system suspend or CPU hotplug. To lower the power number, OFF mode should be adopted for those system resources whenever they can be OFF, A cluster will be OFF if the CPUs in the cluster are all off line, DDR/MU/DB can be OFF if system suspend, IRQ steer can be OFF if the wakeup source is belonged to system controller partition, so wakeup source runtime check is used to determine if IRQ steer can be OFF before system suspend. If resources are powered off for suspend, they should be restored properly after system resume. Signed-off-by: Anson Huang <Anson.Huang@nxp.com>
2019-01-17imx: add imx8qm/imx8qx SRTC SIP runtime service supportAnson Huang

2019-01-04Sanitise includes across codebaseAntonio Nino Diaz
Enforce full include path for includes. Deprecate old paths. The following folders inside include/lib have been left unchanged: - include/lib/cpus/${ARCH} - include/lib/el3_runtime/${ARCH} The reason for this change is that having a global namespace for includes isn't a good idea. It defeats one of the advantages of having folders and it introduces problems that are sometimes subtle (because you may not know the header you are actually including if there are two of them). For example, this patch had to be created because two headers were called the same way: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform to avoid collision."). More recently, this patch has had similar problems: 46f9b2c3a282 ("drivers: add tzc380 support"). This problem was introduced in commit 4ecca33988b9 ("Move include and source files to logical locations"). At that time, there weren't too many headers so it wasn't a real issue. However, time has shown that this creates problems. Platforms that want to preserve the way they include headers may add the removed paths to PLAT_INCLUDES, but this is discouraged.

2018-12-06drivers/console: Link console framework code by defaultJulius Werner
This patch makes the build system link the console framework code by default, like it already does with other common libraries (e.g. cache helpers). This should not make a difference in practice since TF is linked with --gc-sections, so the linker will garbage collect all functions and data that are not referenced by any other code. Thus, if a platform doesn't want to include console code for size reasons and doesn't make any references to console functions, the code will not be included in the final binary. To avoid compatibility issues with older platform ports, only make this change for the MULTI_CONSOLE_API.
