Platform/ARM: Add CadenceQspiNorFlashDeviceLib for NorFlashDxe

2024-05-29T15:45:57+00:00

In N1Sdp platform, the SoC is connected to IOFPGA which has a Cadence Quad SPI (QSPI) controller. This QSPI controller manages the flash chip device via QSPI bus. This patch adds CadenceQspiNorFlashDeviceLib which is used to manage and access the above configuration. Signed-off-by: sahil Reviewed-by: levi.yun Reviewed-by: Sami Mujawar

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: Add P30NorFlashDeviceLib Library

This patch implements functions to interact with P30 NOR Flash. The code is taken from Platform/ARM/Drivers/NorFlashDxe/NorFlash.c file. Signed-off-by: sahil Reviewed-by: Pierre Gondois Reviewed-by: levi.yun Reviewed-by: Sami Mujawar

Platform/ARM: Fix uninitialized variable in RunAxf

2020-04-06T09:49:34+00:00

RunAxf is a shell command used for running an Axf file. The ShellDynCmdRunAxfHandler() loads an ELF file or one processed by the Flashloader. It calls the appropriate loaders to load the file in memory and to obtain the entry point address. The first argument to RunAxfPivot() is the entry point address for the image to execute. The patch https://github.com/tianocore/edk2-platforms/commit/996047695a06167a918b07b22fcd0fbd0def5da6 changes set/way cache maintenance operations to by-VA operation. This patch however introduced an error: 'variable StartElf is not initialized'. Since, StartElf is the first argument to RunAxfPivot(), which is expected to be the entry point address; RunAxfPivot() would end up branching to an invalid address resulting in a crash. Therefore, initialize StartElf to the entry point address before calling RunAxfPivot(). Signed-off-by: Sami Mujawar Reviewed-by: Ard Biesheuvel

Platform/ARM/ArmShellCmdRunAxf: switch to by-VA cache maintenance

2020-03-06T16:53:28+00:00

Currently, the 'runaxf' shell command that exists only on ARM's own development platforms deals with the caches in an unsafe manner, as it relies on set/way maintenance to ensure that the ELF image it has put into memory, as well as the running image itself is visible in memory after the MMU and caches are disabled. So let's switch to by-VA maintenance for the currently running image, as well as the ELF image, and use a helper in assembly to ensure that we are not relying on the stack between the disabling of the MMU and the invocation of the ELF image.

Platform/ARM: Add NetworkPkg/NetworkPkg.dec as the package dependency

NetLib will be moved from MdeModulePkg and NetworkPkg. So, the module that consumes NetLib need to depend on NetworkPkg.dec. Signed-off-by: Liming Gao Cc: Ard Biesheuvel Cc: Leif Lindholm Cc: Michael D Kinney Reviewed-by: Leif Lindholm

Platform/ARM/BdsLib: maintain alignment for DevicePaths

2018-11-26T16:47:50+00:00

DevicePath node types may have any size, and so it is up to the code that manipulates them to ensure that dereferencing them only occurs when the pointer is aligned explicitly. Since BdsConnectAndUpdateDevicePath() has only two callers, one of which itself, we can simply duplicate the device path (similar to how DxeCore's CoreConnectController () does it), and free the pool allocation again on the way out. (Note that the allocation only occurs when the non-recursive path is taken and the function returns EFI_SUCCESS) Contributed-under: TianoCore Contribution Agreement 1.1 Signed-off-by: Ard Biesheuvel Reviewed-by: Laszlo Ersek Tested-by: Thomas Abraham Reviewed-by: Leif Lindholm

Platform/ARM/BdsLib: drop unused functions

2018-11-26T16:47:47+00:00

Clean up BdsLib (which is deprecated and should not be used for future development) by removing all the pieces that are not being used at the moment. After this patch, only BdsLoadImage() remains, and the pieces it relies upon. This function is used by FdtPlatformDxe to load device tree binaries from device paths.

Platform/ARM: import ARM platform specific BdsLib header

2018-11-26T16:47:16+00:00

The BdsLib library has been moved into Platform/ARM a while ago, but the BdsLib.h header was left behind, and so all users in Platform/ARM are still relying on it to be available in ArmPkg. So let's add a copy to Platform/ARM and wire it up, so we can drop it from ArmPkg going forward. Note that the BdsLib implementation included ArmLib.h from ArmPkg without using anything it provides, so drop that false dependency as well.
