The default value of L2CTLR_DATA_RAM_LATENCY is 2, depends to the test result on rk3399, the A72 will need lower voltage for high frequency if it's set to be 5, and almost no effect on performance. Change-Id: I99a6a43edcc0c58f7775c10f4b85669dc3eff66d Signed-off-by: Caesar Wang <wxt@rock-chips.com>

Due to the PMU design, the PMU may not clear the WAKEUP bit after wakeup, therefore, the state machine at the power mode may enter the infinite loop during WFI. There is a solution that we can use the M0 to monitor the WAKEUP bit and clear it during power mode, then the state machine will be recovered immediately. Then, the DUT can exit the WFI normally.

This CL supports add M0 source code to built into the bl31.bin, the goal is that we can load the M0 code binary into SRAM and execute it. We need the M0 help us to clean the power_mode_en bit during the AP PMU enter the state machine with interrupt, and avoid to the AP can not exit the loop forever.

Add the common extra.ld.S and customized rk3399.ld.S to extend to more features for different platforms. For example, we can add SRAM section and specific address to load there if we need it, and the common bl31.ld.S not need to be modified. Therefore, we can remove the unused codes which copying explicitly from the function pmusram_prepare(). It looks like more clear.

rockchip: fixes the clock select and divide register for rk3399

Soby Mathew authored
The values of CP15BEN, nTWI & nTWE bits in SCTLR_EL1 are architecturally unknown if EL3 is AARCH64 whereas they reset to 1 if EL3 is AArch32. This might be a compatibility break for legacy AArch32 normal world software if these bits are not set to 1 when EL3 is AArch64. This patch enables the CP15BEN, nTWI and nTWE bits in the SCTLR_EL1 if the lower non-secure EL is AArch32. This unifies the SCTLR settings for lower non-secure EL in AArch32 mode for both AArch64 and AArch32 builds of Trusted Firmware.

In order to quantify the overall time spent in the PSCI software implementation, an initial collection of PMF instrumentation points has been added. Instrumentation has been added to the following code paths: - Entry to PSCI SMC handler. The timestamp is captured as early as possible during the runtime exception and stored in memory before entering the PSCI SMC handler. - Exit from PSCI SMC handler. The timestamp is captured after normal return from the PSCI SMC handler or if a low power state was requested it is captured in the bl31 warm boot path before return to normal world. - Entry to low power state. The timestamp is captured before entry to a low power state which implies either standby or power down. As these power states are mutually exclusive, only one timestamp is defined to describe both. It is possible to differentiate between the two power states using the PSCI STAT interface. - Exit from low power state. The timestamp is captured after a standby or power up operation has completed. To calculate the number of cycles spent running code in Trusted Firmware one can perform the following calculation: (exit_psci - enter_psci) - (exit_low_pwr - enter_low_pwr). The resulting number of cycles can be converted to time given the frequency of the counter. Change-Id: Ie3b8f3d16409b6703747093b3a2d5c7429ad0166 Signed-off-by: dp-arm <dimitris.papastamos@arm.com>

Fix documentation of bootwrapper boot on juno
-
Antonio Nino Diaz authored
The user guide incorrectly claimed that it is possible to load a bootwrapped kernel over JTAG on Juno in the same manner as an EL3 payload. In the EL3 payload boot flow, some of the platform initialisations in BL2 are modified. In particular, the TZC settings are modified to allow unrestricted access to DRAM. This in turn allows the debugger to access the DRAM and therefore to load the image there. In the BL33-preloaded boot flow though, BL2 uses the default TZC programming, which prevent access to most of the DRAM from secure state. When execution reaches the SPIN_ON_BL1_EXIT loop, the MMU is disabled and thus DS-5 presumably issues secure access transactions while trying to load the image, which fails. One way around it is to stop execution at the end of BL2 instead. At this point, the MMU is still enabled and the DRAM is mapped as non-secure memory. Therefore, the debugger is allowed to access this memory in this context and to sucessfully load the bootwrapped kernel in DRAM. The user guide is updated to suggest this alternative method.

This patch adds necessary updates for building and running Trusted Firmware for AArch32 to user-guide.md. The instructions for running on both `FVP_Base_AEMv8A-AEMv8A` in AArch32 mode and `FVP_Base_Cortex-A32x4` models are added. The device tree files for AArch32 Linux kernel are also added in the `fdts` folder. Change-Id: I0023b6b03e05f32637cb5765fdeda8c8df2d0d3e

The `fvp-base-gicv3-psci` and `fvp-foundation-gicv3-psci` device tree source files did not have psci node entries for `system off` and `system reset`. Also the DTS files included `rtsm_ve-motherboard-no_psci.dtsi` instead of `rtsm_ve-motherboard.dtsi`. As a result, the Linux kernel failed to invoke the PSCI_SYSTEM_OFF/RESET API when being shutdown/reset. This patch corrects this problem and also updates the corresponding DTB files. This patch also removes `rtsm_ve-motherboard-no_psci.dtsi` and `fvp-foundation-motherboard-no_psci.dtsi` files as they are no longer used. Change-Id: I8ba61a1323035f7508cae663bb490ac0e8a64618
