- /* Note: gas handles memory addresses in 16 bit code very poorly.
- * In particular it doesn't appear to have a directive allowing you
- * associate a section or even an absolute offset with a segment register.
- *
- * This means that anything except cs:ip relative offsets are
- * a real pain in 16 bit mode. And explains why it is almost
- * imposible to get gas to do lgdt correctly.
- *
- * One way to work around this is to have the linker do the
- * math instead of the assembler. This solves the very
- * pratical problem of being able to write code that can
- * be relocated.
- *
- * An lgdt call before we have memory enabled cannot be
- * position independent, as we cannot execute a call
- * instruction to get our current instruction pointer.
- * So while this code is relocateable it isn't arbitrarily
- * relocatable.
- *
- * The criteria for relocation have been relaxed to their
- * utmost, so that we can use the same code for both
- * our initial entry point and startup of the second cpu.
- * The code assumes when executing at _start that:
- * (((cs & 0xfff) == 0) and (ip == _start & 0xffff))
- * or
- * ((cs == anything) and (ip == 0)).
- *
- * The restrictions in reset16.inc mean that _start initially
- * must be loaded at or above 0xffff0000 or below 0x100000.
- *
- * The linker scripts computs gdtptr16_offset by simply returning
- * the low 16 bits. This means that the intial segment used
- * when start is called must be 64K aligned. This should not
- * restrict the address as the ip address can be anything.

- * From Intel Vol. III Section 9.12.4, the Range Size and Base Alignment has some kind of requirement:
- * 1. The range size must be 2^N byte for N >= 12 (i.e 4KB minimum).
- * 2. The base address must be 2^N aligned, where the N here is equal to the N in previous
- * requirement. So a 8K range must be 8K aligned not 4K aligned.
- *
- * These requirement is meet by "decompositing" the ramsize into Sum(Cn * 2^n, n = [0..N], Cn = [0, 1]).
- * For Cm = 1, there is a WB range of 2^m size at base address Sum(Cm * 2^m, m = [N..n]).
- * A 124MB (128MB - 4MB SMA) example:
- * ramsize = 124MB == 64MB (at 0MB) + 32MB (at 64MB) + 16MB (at 96MB ) + 8MB (at 112MB) + 4MB (120MB).
- * But this wastes a lot of MTRR registers so we use another more "aggresive" way with Uncacheable Regions.
- *
- * In the Uncacheable Region scheme, we try to cover the whole ramsize by one WB region as possible,
- * If (an only if) this can not be done we will try to decomposite the ramesize, the mathematical formula
- * whould be ramsize = Sum(Cn * 2^n, n = [0..N], Cn = [-1, 0, 1]). For Cn = -1, a Uncachable Region is used.
- * The same 124MB example:
- * ramsize = 124MB == 128MB WB (at 0MB) + 4MB UC (at 124MB)
- * or a 156MB (128MB + 32MB - 4MB SMA) example:
- * ramsize = 156MB == 128MB WB (at 0MB) + 32MB WB (at 128MB) + 4MB UC (at 156MB)
