Booloader checksum too big #5330
Description
The code to create the sha256 of the bootloader is creating more unqiue hash values than expected, we suspect this might be for devices that have not specifically done a full erase of the memory so unused memory might be throwing off the calculations. The original logic was for the full memory that could be used for bootloader would be included, but perhaps this needs to be reduced to actually reflect how much is actually used. It appears to end at B9A0 for the bootloader we use for the esp32 classic
