2020-05-10imx8mp: Set default SNSR25C for TMU probe1Ye Li
So far u-boot only load SNSR25C for TMU main probe (probe 0). However, kernel enables two probes. So it also needs to set default SNSR25C of TCALIV1 for blank samples. Reviewed-by: Peng Fan <peng.fan@nxp.com> Signed-off-by: Ye Li <ye.li@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com>

2019-12-09imx8m: fix rom version check to unbreak some B0 chipsPatrick Wildt
Recently the version check was improved to be able to determine that we're running on SoC revision 2.1. A check for B0 was tightened so that it now must equal 0x20 instead of being bigger than 0x20. On some B0 chips the value returned is 0x1020 instead of 0x20. This means even though it's B0, the check will fail and code relying on the correct chip revision will make wrong decisions. There is no documentation of those bits, but it seems that NXP always uses a byte to encode the revision. Thus remove the upper bits to fix the regression.
