Thus any changes in CLM table/creation of new CLM table for any product/customer requires spinning a separate firmware build. Supporting several FW build requests was not scalable for vendor. Hence Cypress have designed a new architecture to build and load clm as a separate blob file from firmware. Fix: Cypress provided DHD patch to support loading clm.blob file after loading firmware to chip, in Mycase 403591. With this patch, firmware with built-in clm works as is, firmware with external clm.blob has to be used with corresponding products clm.blob in CONFIG_BCMDHD_CLM_PATH. If clm.blob file is not present on DUT, once firmware is loaded driver validates currently set country code in fw. If it is not valid (true for cases like firmware which do not have built-in CLM), then driver aborts wifi initialization.
