We're moving from wide rotuines to narrow +routines. The UTC-2 this code is written for is a bad match for +wchar_t which is an int. It's a much better match for plain narrow +characters on FreeBSD. So we pretend that CHAR16 for these files is +really char * (ASCII). + +Next, we have have to convert the Unicode printf that this code +expects to FreeBSD's printf. %g means "Print the GUID" and %a means +"print the ASCII string." so we mechanically convert them. Once we've +done that we can compare efivar-dp-*.c to its source to see what's +changed. Because we go through this indirection, I've done that +outside of svn. To upgrade you have to do these files by hand. You +have to go through and make routines static. + +uefi-*.[ch] are internal routines to support this. They've been copied +from EDK2 as well, but in a more hap-hazard manner. This was a trade +off between ease of implementation / upgrade vs pulling in too much +since less than half of any file was needed. + +efi-osdep.h shims the EDK2 types to FreeBSD's types. It's included by +ProcessorBind.h which EDK2 uses to define the CPU. We keep it separate +from uefi-dplib.h to allow better sharing. + +uefi-dplib.h shims the EDK2 routines that are needed to FreeBSD's +routines.
