Re: Cannot successfully jump to the UEFI Boot Loader in the normal world with the RME enabled FVP_Base_RevC_2xAEMvA

by Erhu Feng

Hi, Thanks for the detailed documentation about how to enable RME in tf-a. I try to replace the tftf.bin with the normal boot firmware (edk2) to load the Linux in the normal world, but it fails. The log message from terminal_0 is shown below: INFO: RMM init start. INFO: RMM init end. INFO: BL31: Preparing for EL3 exit to normal world INFO: Entry point address = 0x88000000 INFO: SPSR = 0x3c9 I found a possible solution from the archives: [https://lists.trustedfirmware.org/archives/list/tf-a@lists.trustedfirmware.…]. I try to modify the dts file under edk2-platform/Platform/ARM/VExpressPkg/DeviceTree/ to change the DDR memory range, which is similar to the modification for RME in [https://github.com/ARM-software/arm-trusted-firmware/blob/master/fdts/fvp-b…], but it does not solve the problem. So, how can I boot Linux in the normal world with RME enabled? Thanks,

Addition of write() capability to IO MTD layer

by brian.neely＠analog.com

Hello, A project I’m working on requires write capability for a NOR flash device in BL2 (to update a small boot mux partition). I am considering adding this capability to the IO MTD layer (https://github.com/ARM-software/arm-trusted-firmware/blob/master/drivers/io…), but before doing so wanted to confirm this is in line with the architecture of this subsystem. Can someone confirm if this is an acceptable change? Regards, Brian

Version 1.2.12 of zlib was released

by mikemcternan＠google.com

Hi! It looks like TF-A contains zlib 1.2.11 e.g. https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tree/lib/zlib/z… zlib.net gives their last release as 1.2.12 (March 27, 2022) with the following changelog: "Fix a deflate bug when using the Z_FIXED strategy that can result in out-of-bound accesses. Fix a deflate bug when the window is full in deflate_stored(). Speed up CRC-32 computations by a factor of 1.5 to 3. Use the hardware CRC-32 instruction on ARMv8 processors. Speed up crc32_combine() with powers of x tables. Add crc32_combine_gen() and crc32_combine_op() for fast combines. Due to the bug fixes, any installations of 1.2.11 should be replaced with 1.2.12." I'm not sure if this is significant as I couldn't find usages of deflate, but thought I would mention it in case others are relying on this functionality and wish to update. Kind regards, Mike

synopsis emcc adma2/3 modes

by gauravverma999＠gmail.com

Hello all, I need to load Bl2 boot image file from emmc interface from 'Synopsys DesignWare Cores Mobile Storage Host Controller'. I can see an existing emmc driver for synopsis controller but it seems to have only support SDMA mode and not ADMA2 and ADMA3 modes. https://github.com/ARM-software/arm-trusted-firmware/blob/master/drivers/sy… Is my understanding correct. Is there a specific reason why ADMA2/3 modes are not supported in existing driver. Any plan to update them soon? I can see adma2/3 mode support available in Linux driver though. https://github.com/torvalds/linux/blob/master/drivers/mmc/host/sdhci-of-dwc…
