Re: [U-Boot] [PATCH v2 7/7] imx: add status reporting for HAB status

Hi,

+bool is_hab_enabled(void) +{

• struct ocotp_regs *ocotp = (struct ocotp_regs *)OCOTP_BASE_ADDR;
• struct fuse_bank *bank = &ocotp->bank[0];
• struct fuse_bank0_regs *fuse =

• (struct fuse_bank0_regs *)bank->fuse_regs;
  

• uint32_t reg = readl(&fuse->cfg5);
• return (reg & 0x2) == 0x2;

+}

With the exception of that function and the required structure definitions, the whole code also works with i.MX53 (tested with LOCO board), too. Also AN4581 [1] that describes HAB doesn't differentiate between i.MX53 and i.MX6 in that case as they both use HAB v4.

I think you have more experience how to organize the code (I added a few symlinks and modified only the Makefile, but I guess that symlink are not the best solution).
