We're moving from wide rotuines to narrow 13314926Simproutines. The UTC-2 this code is written for is a bad match for 14314926Simpwchar_t which is an int. It's a much better match for plain narrow 15314926Simpcharacters on FreeBSD. So we pretend that CHAR16 for these files is 16314926Simpreally char * (ASCII). 17314926Simp 18314926SimpNext, we have have to convert the Unicode printf that this code 19314926Simpexpects to FreeBSD's printf. %g means "Print the GUID" and %a means 20314926Simp"print the ASCII string." so we mechanically convert them. Once we've 21314926Simpdone that we can compare efivar-dp-*.c to its source to see what's 22314926Simpchanged. Because we go through this indirection, I've done that 23314926Simpoutside of svn. To upgrade you have to do these files by hand. You 24314926Simphave to go through and make routines static. 25314926Simp 26314926Simpuefi-*.[ch] are internal routines to support this. They've been copied 27314926Simpfrom EDK2 as well, but in a more hap-hazard manner. This was a trade 28314926Simpoff between ease of implementation / upgrade vs pulling in too much 29314926Simpsince less than half of any file was needed. 30314926Simp 31314926Simpefi-osdep.h shims the EDK2 types to FreeBSD's types. It's included by 32314926SimpProcessorBind.h which EDK2 uses to define the CPU. We keep it separate 33314926Simpfrom uefi-dplib.h to allow better sharing. 34314926Simp 35314926Simpuefi-dplib.h shims the EDK2 routines that are needed to FreeBSD's 36314926Simproutines. This is relatively easy since we map all the UCS-2 routines 37314926Simpto simple char * routines. 38314926Simp 39314926SimpRESIST THE URGE TO CLEAN UP THESE FILES. 40
