2017-07-26arm: mach-keystone: Updates mon_install for K2G HSMadan Srinivas
On early K2 devices (eg. K2HK) the secure ROM code does not support loading secure code to firewall protected memory, before decrypting, authenticating and executing it. To load the boot monitor on these devices, it is necessary to first authenticate and run a copy loop from non-secure memory that copies the boot monitor behind firewall protected memory, before decrypting and executing it. On K2G, the secure ROM does not allow secure code executing from unprotected memory. Further, ROM first copies the signed and encrypted image into firewall protected memory, then decrypts, authenticates and executes it. As a result of this, we cannot use the copy loop for K2G. The mon_install has to be modified to pass the address the signed and encrypted secure boot monitor image to the authentication API. For backward compatibility with other K2 devices and K2G GP, the mon_install API still supports a single argument. In this case the second argument is set to 0 by u-boot and is ignored by ROM Signed-off-by: Thanh Tran <thanh-tran@ti.com> Signed-off-by: Madan Srinivas <madans@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>
2016-10-01ARM: keystone2: Add support for parsing monitor headerLokesh Vutla
Given that boot monitor image is being generated to a specific target location depending on the SoC and U-boot relies on addr_mon env variable to be aligned with boot monitor target location. When ever the target address gets updated in boot monitor, it is difficult to sync between u-boot and boot monitor and also there is no way to update user that boot monitor image is updated. To avoid this problem, boot monitor image is being generated with mkimage header. Adding support in mon_install command for parsing this header.

2016-03-16ARM: keystone2: Split monitor code / command codeTom Rini
When we switch to including all linker lists in SPL it is important to not include commands as that may lead to link errors due to other things we have already discarded. In this case, we split the code for supporting the monitor out from the code for loading it.

2015-07-27keystone2: add wfi in to the core_spin loopVitaly Andrianov
When core A turning of core B, via tetris DPSC it places the core B DPSC into transitional state. The core B has to execute wfi instruction to move its DPSC to the OFF state. This patch add such instruction. Signed-off-by: Vitaly Andrianov <vitalya@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>
