Enable ARM_XLAT_TABLES_LIB_V1 as ZynqMP is using v1 library of translation tables. With upstream patch d323af9e , the usage of MAP_REGION_FLAT is referring to definition in file include/lib/xlat_tables/xlat_tables_v2.h but while preparing xlat tables in lib/xlat_tables/xlat_tables_common.c it is referring to include/lib/xlat_tables/xlat_tables.h which is v1 xlat tables. Also, ZynqMP was using v1 so defined ARM_XLAT_TABLES_LIB_V1 to use v1 xlat tables everywhere. This fixes the issue of xlat tables failures as it takes v2 library mmap_region structure in some files and v1 in other files.

This patch adds ATF support for AES data blob encrypt/decrypt. ATF establishes a path to send the address of the structure to the xilsecure, so that it will pick addresses of the data and performs the requested operation (encrypt/decrypt) and puts the result in load address. where structure contains - Data blob src address - load address - IV address - Key address - this will actual key addr in case of KUP else it will be zero. - Data-size - Aes-op type - KeySrc Signed-off-by: Kalyani Akula <kalyani.akula@xilinx.com> Signed-off-by: Siva Durga Prasad Paladugu <siva.durga.paladugu@xilinx.com>

PLL type clock is enabled by FSBL on boot-up. PMUFW enable/disable them based on their user count. So, it should not be handled from ATF. Put PLL type clock into bypass and reset mode only while changing PLL rate (FBDIV).

WDT used by APU is FPD_WDT. FPD WDT clock is controlled by FPD_SLCR.WDT_CLK_SEL register. Correct the same in WDT clock database. As per FPD_SLCR.WDT_CLK_SEL register, there can be only two parents of WDT clock not three. Fix the same by correcting it's parents in clock database.

To make ULPI transceiver work, a HIGH - LOW - HIGH pulse needs to be given to resetb pin of ULPI chip. In ZYNQMP, this resetb pin is being driven by BOOT MODE PIN 1. The BOOT MODE PIN's are controlled by BOOT_PIN_CTRL register present in CRL_APB address region. Since CRL_APB can be resticted to secure access, this pin should be controlled by ATF. This patch adds the support for the same. Signed-off-by: Anurag Kumar Vulisha <anuragku@xilinx.com> Signed-off-by: Siva Durga Prasad Paladugu <siva.durga.paladugu@xilinx.com>

Currently in Linux maximum number of clocks is hard-coded and so it needs to allocate static memory. It can get actual clock number after querying all clock names by special clock name string. Add new query data parameter to get actual number of clocks so Linux can get actual clock numbers in advance. Signed-off-by: Rajan Vaja <rajan.vaja@xilinx.com>

Change arm_setup_page_tables() to take a variable number of memory regions. Remove coherent memory region from BL1, BL2 and BL2U as their coherent memory region doesn't contain anything and therefore has a size of 0. Add check to ensure this doesn't change without us knowing. Change-Id: I790054e3b20b056dda1043a4a67bd7ac2d6a3bc0 Signed-off-by: Daniel Boulby <daniel.boulby@arm.com>

RFC4122 defines that fields are stored in network order (big endian), but TF-A stores them in machine order (little endian by default in TF-A). We cannot change the future UUIDs that are already generated, but we can store all the bytes using arrays and modify fiptool to generate the UUIDs with the correct byte order.

The vcu disable bit in efuse ipdisable register is valid only if PL powered up so, consider PL powerup status for determing EG/EV part. If PL is not powered up, display EG/EV as a part of string. The PL powerup status will be filled by pmufw based on PL PROGB status in the 9th bit of version field.This patch also used IPI to get this info from pmufw instead of directly accessing the registers. Accessing this info from pmufw using IPI fixes the issue of PMUFW access denied error for reading IPDISABLE register. Signed-off-by: Siva Durga Prasad Paladugu <sivadur@xilinx.com>

Existing code blocks each IPI send request in ipi_mb_notify() function till pmu clears respective bit in ipi observation register. After sending PM_SYSTEM_SHUTDOWN request to PMU, PMU will restart APU. While PMU is restarting APU, ATF is running out of OCM, which can cause read/write hang from/to OCM. There is no need to wait for notification from PMU in case of SystemShutdown request in ATF, as APU is going to restart. This patch fixes APU only restart issue.

Xilinx now requires the PMU FW when using ATF, so it doesn't make sense to maintain checks for the PMU FW in ATF. This also means that cases where ATF came up before the PMU FW (such as on QEMU) ATF will now hang waiting for the PMU FW instead of aborting.

psci system_reset and system_off calls now retrieve shutdown scope on the fly. The default scope is system, but it can be changed by calling pm_system_shutdown(2, scope) Until full support for different restart scopes becomes available with PSCI 1.1 this change allows users to set the reboot scope to match their application needs. Possible scope values: 0 - APU subsystem: does not affect RPU, PMU or PL 1 - PS only: shutdown/restart entire PS without affecting PL 2 - System: shutdown/restart applies to entire system Signed-off-by: Siva Durga Prasad Paladugu <sivadur@xilinx.com> Signed-off-by: Davorin Mista <davorin.mista@aggios.com>
