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 https://eur01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fpatch work.ozlabs.org%2Fproject%2Fuboot%2Fpatch%2F20220616101009.809953-

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...
I have sent a V4 which fixes the error for powerpc platforms.
Thanks - I merge and I start a new CI.
Stefano
Thanks Gaurav Jain

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:

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 ?
