Measured boot and external TPM modules

by Ramon Fried

Hi, I'm currently working on porting TFA to our upcoming SOC. We plan to support Measured boot using external I2C TPM module. I'm wondering about the implementation of that in BL1. Do you think that I need to write the measurements directly to the I2C module in BL1 ? I'm asking because I would like to have the least source of problems in BL1 which I can't upgrade. I thought of storing the measurements in secure RAM and perhaps copy later. Would love to hear your thoughts. PS. Actually I would love to have the option to choose to implement TPM also in SW (fTPM using optee - as was done in the POC). I think that if I store the measurement of BL2 in secure RAM I can later change the specific TPM while upgrading only BL2/BL31... Thanks, Ramon

[REGRESSION] v2.7-rc0 broken for STM32MP boards: lxa-mc1, avenger96, odyssey

by Ahmad Fatoum

Hello Yann, Hello Pascal, I've tried booting v2.7-rc0 on the lxa-mc1 and TF-A panics: NOTICE: CPU: STM32MP157C?? Rev.B NOTICE: Model: Linux Automation MC-1 board ERROR: regul ldo3: max value 750 is invalid PANIC at PC : 0x2ffeebb7 because the driver takes great offense at the content of the device tree. The parts in question were copy-pasted from ST DTs, but those ST DTs were fixed by commit 67d95409baae ("refactor(stm32mp1-fdts): update regulator description"). I can understand ST hesistancy to touch device trees of 'unofficial' boards, but I would appreciate that new features then, such as this regulator sanity checking, be made optional and off by default to not needlessly break other boards. Thanks, Ahmad -- Pengutronix e.K. | | Steuerwalder Str. 21 | http://www.pengutronix.de/ | 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 |

Floating point math

by Bartus, Dan

We are using an arm ARCH-64 (A55) and we need to do some floating point math in BL2. It seems this is not enabled. Is there a reason why I cannot do FP math (security issue?) and if I can, how do I enable it? I am seeing this error when I use floats "-mgeneral-regs-only" thanks
