Harrison Mutai	c7e698cfde	fix(cpus): workaround for Cortex-X3 erratum 2615812 ... Cortex-X3 erratum 2615812 is a Cat B erratum that applies to revisions r0p0, r1p0, and r1p1, and is still open. The workaround is to disable the use of the Full Retention power mode in the core (setting WFI_RET_CTRL and WFE_RET_CTRL in CORTEX_X3_IMP_CPUPWRCTLR_EL1 to 0b000).

Boyan Karatotev	7954412694	fix(cpus): workaround for Cortex-X3 erratum 2313909 ... Cortex-X3 erratum 2313909 is a Cat B erratum that applies to revisions r0p0 and r1p0, and is fixed in r1p1. The workaround is to set CPUACTLR2_EL1[36] to 1 before the power down sequence that sets CORE_PWRDN_EN. This allows the cpu to retry the power down and prevents the deadlock. TF-A never clears this bit even if it wakes up from the wfi in the sequence since it is not expected to do anything but retry to power down after and the bit is cleared on reset.

Boyan Karatotev	cf58b2d41c	chore: rename Makalu ELP to Cortex-X3 ... The Cortex-X3 cpu port was developed before its public release when it was known as Makalu ELP. Now that it's released we can use the official product name. Signed-off-by: Boyan Karatotev <boyan.karatotev@arm.com> Change-Id: Iebb90cf2f77330ed848a3d61c5f6928942189c5a	2022-10-27 09:41:00 +01:00
