Hi Stefano
this patch is fixing dcache issue in fsl_rsa.c
The thread changed name, I mean "crypto/fsl: fsl_hash: Fix crash in flush dcache"
Error reported is in drivers/crypto/fsl/fsl_hash.c addr = (addr << 32) | sec_in32(&ctx->sg_tbl[i].addr_lo);
reported error is fixed in [v3] crypto/fsl: fsl_hash: Fix crash in flush dcache http://patchwork.ozlabs.org/project/uboot/patch/20220616101009.809953-1-gaur...
Give an another attempt, it fails and it is quite clear why:
+#ifdef CONFIG_CAAM_64BIT + addr = sec_in32(&ctx->sg_tbl[i].addr_hi); + addr = (addr << 32) | sec_in32(&ctx->sg_tbl[i].addr_lo); +#else
Fine with ARM and ARM64. In Kconfig:
config CAAM_64BIT bool default y if PHYS_64BIT && !ARCH_IMX8M && !ARCH_IMX8 help Select Crypto driver for 64 bits CAAM version
That is ok until powerpc are built that sets PHYS_64BIT. Then build fails with:
powerpc: + T4240RDB_SDCARD +drivers/crypto/fsl/fsl_hash.c: In function 'caam_hash_finish': +drivers/crypto/fsl/fsl_hash.c:151:30: error: left shift count >= width of type [-Werror=shift-count-overflow] + 151 | addr = (addr << 32) | sec_in32(&ctx->sg_tbl[i].addr_lo); + | ^~ +cc1: all warnings being treated as errors
And well, compiler is right...

Hi Stefano
This patch is put into state "changes requested". But it is a different patch in fsl_rsa. There is no change requested with this patch.
Something went wrong - I have applied this patch to push to 2022.07, but in CI I get the same errors I found before, that is PowerPC build was broken:
https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fsource.d enx.de%2Fu-boot%2Fcustodians%2Fu-boot-imx%2F- %2Fjobs%2F457090&data=05%7C01%7Cgaurav.jain%40nxp.com%7C98808 23b97ef4669f51108da599feffc%7C686ea1d3bc2b4c6fa92cd99c5c301635%7C0 %7C0%7C637920840703403368%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4 wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C %7C%7C&sdata=FGDL9eBnjyUDc423myN4jVoK7QD9VZiitvZao6mz04s%3D &reserved=0
I hadn't time to check this, and I suppose that issue is not yet fixed and I drop the patch from MR (Layerscape is broken, too), that is V3 has not fixed CI as in V2. Or is there anothe rpatch I had to pick up ?
Best regards, Stefano

Please always explain what changed in the current version of the patch.
I assume you fixed the build error found in CI, correct?
This is a different patch in fsl_rsa.c I will send a different patch for the error reported by you.
Ouch...I have misunderstood. Well, then I willwait for your patch..
