    mailbox: mailbox-test: allow reserved areas in SRAM · db4d22c0
    Sudeep Holla authored
    When CONFIG_SRAM is enable and the SRAM region is found, the entire SRAM
    region resource is requested and marked as occupied by SRAM driver even
    if certain parts of regions is marked reserved.
    
    It's quite possible that a small region of the SRAM is reserved for all
    the mailbox communication and hence it may fail to request the region
    as it's already marked busy region.
    
    This patch tries to just do a ioremap of this mailbox memory region if
    it finds it busy.
