Subject: [PATCH] lrdp-v2: automatically lookup addresses when needed
Add support to RamDump.virt_to_phys for automatically looking up
addresses of symbols when a string is passed in. This will simplify code
that uses the RamDump.read_* routines.
Old way:
mydata_addr = ramdump.addr_lookup('data_var')
mydata2_addr = ramdump.addr_lookup('data2_var')
mydata = ramdump.read_word(mydata_addr)
mydata2 = ramdump.read_word(mydata2_addr)
New way:
mydata = ramdump.read_word('data_var')
mydata2 = ramdump.read_word('data2_var')
Of course, the "Old way" will still work.
