Platform,Silicon: drop redundant uses of PcdArmArchTimerFreqInHz

2024-06-21T11:31:20+00:00

PcdArmArchTimerFreqInHz is about to be removed, as it is now obsolete. Some platforms already explicitly set it to 0, which is the default. And some modules reference it in their .inf without actually ever using it. Drop these redundant uses first.

Platform/ARM: Add optional provision to fetch and print NOR Flash info

2024-05-29T15:45:55+00:00

This patch adds an optional functionality in NorFlashDxe to fetch and print NOR Flash information from NorFlashInfoLib using its JEDEC ID. NOR Flash libraries will implement a function "NorFlashReadID" which will fetch and return JEDEC ID. This JEDEC ID can be then printed along with the NOR Flash info by NorFlashInfoLib. If this functionality is not needed then the function can just return EFI_UNSUPPORTED. Signed-off-by: sahil Reviewed-by: Pierre Gondois Reviewed-by: levi.yun Reviewed-by: Sami Mujawar

Platform/ARM/NorFlashDxe: Switch from NorFlash.c to NorFlashDeviceLib

2024-05-29T15:45:54+00:00

NorFlashDeviceLib can be used to provide implementations of different NOR Flash to NorFlashDxe, i.e. NorFlashDxe links with NorFlashDeviceLib and the platforms can specify their respective NorFlashDeviceLib instances. This patch adds the following major changes: 1. Adds changes in NorFlashDxe to look for NorFlashDeviceLib instead of NorFlash.c for flash specific implementation 2. Remove NorFlash.c and NorFlash.h as they are no longer required. 3. Add changes to platform description files to provide P30NorFlashDeviceLib as NorFlashDeviceLib Signed-off-by: sahil Reviewed-by: Pierre Gondois Reviewed-by: levi.yun Reviewed-by: Sami Mujawar

Platform/ARM: Juno: Generate _CPC objects for JunoR2

2024-01-30T14:15:55+00:00

The SsdtCpuTopologyGenerator can generate _CPC objects. This is done by querying the SCP for the relevant performance state information through SCMI. CM_ARM_CPC_INFO are then populated and used to generate _CPC objects in the Ssdt Cpu topology. Use the DynamicTablesScmiInfoLib and add the handling to generate _CPC information. Note that using _CPC is only possible if SCP is correctly tuned to advertise performance levels on an abstract and unified scale. A basic check is done to prevent the _CPC generation otherwise. Perf level values used for testing: - little CPUs OPPs: [181, 322, 383] * 1000 - big CPUs OPPs: [512, 833, 1024] * 1000 Also make use of the newly added PcdDevelopmentPlatformRelaxations and add a new ENABLE_CPC build parameter ('-D ENABLE_CPC') to enable CPC generation.

Platform/Arm: Disable memmap platform timers for JunoR0

2023-09-11T11:16:38+00:00

Juno includes a system-level wakeup timer which is an implementation of the ARM Generic Timer architecture. The CNTCTL frame contains some registers that are accessible using a Non-Secure access. Juno R0 incorrectly limits these accesses to Secure access only. This issue is documented in the Juno Errata 832219: APB port security breaks SBSA compliance https://developer.arm.com/documentation/epm008857/latest This results in a crash when the OS tries to access these registers. Therefore, disable memory mapped platform timers for Juno R0.

Platform/ARM/JunoPkg: Bump the FV size to 2MB

2023-04-12T11:27:38+00:00

Increase the FV size from 996KB to 2MB. This allows more features to be accommodated in the firmware image, such as HTTPS boot. It also allows a NOOPT build to be added, which is useful for source-level debugging. Add a comment explaining that the size chosen doesn't reflect the actual size of the Flash Device but is instead selected to reduce the amount of time needed to copy the image to the target. Update the BlockSize and NumBlocks to reflect the 256KB block size of the main area on the Juno R2. Signed-off-by: Rebecca Cran

Platform/ARM/JunoPkg: Set PcdArmArchTimerFreqInHz to 0 to read from CNTFRQ_EL0

2023-02-21T08:46:18+00:00

If PcdArmArchTimerFreqInHz is zero, the value of the timer frequency will be read from CNTFRQ_EL0. Avoid hard-coding the value in ArmJuno.dsc and instead let the ArmArchTimerLib driver read it from the SoC. Signed-off-by: Rebecca Cran Reviewed-by: Ard Biesheuvel
