We're moving from wide rotuines to narrow 13routines. The UTC-2 this code is written for is a bad match for 14wchar_t which is an int. It's a much better match for plain narrow 15characters on FreeBSD. So we pretend that CHAR16 for these files is 16really char * (ASCII). 17 18Next, we have have to convert the Unicode printf that this code 19expects to FreeBSD's printf. %g means "Print the GUID" and %a means 20"print the ASCII string." so we mechanically convert them. Once we've 21done that we can compare efivar-dp-*.c to its source to see what's 22changed. Because we go through this indirection, I've done that 23outside of svn. To upgrade you have to do these files by hand. You 24have to go through and make routines static. 25 26uefi-*.[ch] are internal routines to support this. They've been copied 27from EDK2 as well, but in a more hap-hazard manner. This was a trade 28off between ease of implementation / upgrade vs pulling in too much 29since less than half of any file was needed. 30 31efi-osdep.h shims the EDK2 types to FreeBSD's types. It's included by 32ProcessorBind.h which EDK2 uses to define the CPU. We keep it separate 33from uefi-dplib.h to allow better sharing. 34 35uefi-dplib.h shims the EDK2 routines that are needed to FreeBSD's 36routines. This is relatively easy since we map all the UCS-2 routines 37to simple char * routines. 38 39RESIST THE URGE TO CLEAN UP THESE FILES. 40
