[PATCH] fix(mmc): remove redundant reset_to_idle call

by Baruch Siach

mmc_enumerate() is the only caller of mmc_send_op_cond(). mmc_enumerate() calls mmc_reset_to_idle() just before calling mmc_send_op_cond(). No need to do that again in mmc_send_op_cond().

Is NS_BL1U necessary to do FWU ?

by Jun.Chen(陳奕昕)

Hi, In ARM TBBR, there is a requirement “R0100_TBBR_AFM_FLASHING” (The AP firmware must switch to the Non-Trusted world for executing the SoC firmware loader), But there is no requirement for secure boot as long as I finish chain if ROT verification. So, can I implement FWU in BL2 which is verified and load from BL1 (ROM)? For example, BL1(ROM) -> Load and verify BL2U with new image from SD to secure RAM -> execute BL2U in Secure RAM then write new image to NAND flash Best regards, Jun

Checking SIP Service Calls range

by Michal Simek

Hi, I have one question about SIP Service Calls range and it's range checking. Based on DEN0028E SIP Service Calls ranges are 0x82000000-0x8200FFFF SMC32: SiP Service Calls 0xC2000000-0xC200FFFF SMC64: SiP Service Calls That's the ranges which we are using for implementing SOC specific SMC handlers and I found that in past it was also added code which is out of this range. Specifically in Xilinx ZynqMP you can see code like this if (is_em_fid(smc_fid)) { return em_smc_handler(smc_fid, x1, x2, x3, x4, cookie, handle, flags); } where EM range is 0x820e0001- 0x820e0003 is out of our range which is assigned to us. But there is no failure at all that we are out of ranged in spec. Shouldn't this be enforced by core itself? That's why I just wanted to know your opinion about it. We will definitely implement better masking to find out that 0x00fe0000 are all zeros. But that bit 16 is based on DEN0028E related to smcccv1.3 which I think we are not supporting now that's why should be 0 too. But definitely some information about this bit should be useful.

Coding guidelines update: Discouraging usage of weak functions

by Sandrine Bailleux

Hi all, As you may know, the TF-A project historically used to make heavy use of weak functions. The code base has numerous examples of them. However, based on previous discussions, I think we have general consensus in the TF-A community that the disadvantages of weak functions outweigh their benefits and for this reason we should discourage introducing new ones. In practice, I think this policy is already enforced most of the time in code reviews but I've now posted a patch that makes it explicit in the project's coding guidelines and provide the rationale behind it. https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/19398 Note that TF-A maintainers would still be responsible for enforcing this policy, as the CI system won't flag that for them, mainly because I think there might be legitimate cases for weak functions in rare instances so we'd get some false positives from such checks. We (at Arm) have got plans to gradually convert existing weak functions to strongly-defined implementations across the code base but this will take time. Like I said, I don't expect this change to be too controversial but please raise any concerns you may have in this email thread or on Gerrit. Best regards, Sandrine
