* Because the BTX mini-kernel now uses flat memory mode and clientsRuslan Ermilov2006-10-295-10/+10
| | | | | | | | | | | | | | | | | | | are no longer limited to a virtual address space of 16 megabytes, only mask high two bits of a virtual address. This allows to load larger kernels (up to 1 gigabyte). Not masking addresses at all was a bad idea on machines with less than >3G of memory -- kernels are linked at 0xc0xxxxxx, and that would attempt to load a kernel at above 3G. By masking only two highest bits we stay within the safe limits while still allowing to boot larger kernels. (This is a safer reimplmentation of sys/boot/i386/boot2/boot.2.c rev. 1.71.)

| | | | | | | | | | | Massive update. The highlights: o dramatically cut memory usage by writing better, less intertwingled code. o implement booting off mmc/sd cards (sd only tested one at the moment) o start to split out board specific stuff for boot2. Notes: svn path=/head/; revision=163533

* - Fix a couple of improper uses of leal in the previous space savingJohn Baldwin2006-10-051-5/+7
| | | | | | | | | | | | | | | | | | commits. For some reason I thought the scale factor was a shift count rather than the multiplicand (that is, I thought leal (%eax,%edx,4) was going to generate %eax + %edx << 4 rather than %eax + %edx * 4). What I need is to multiply by 16 to convert a real-mode (seg, offset) tuple into a flat address. However, the max multiplicand for scaled/index addressing on i386 is 8, so go back to using a shl and an add. - Convert two more inter-register mov instructions where we don't need to preserve the source register to xchg instructions to keep our space savings.

| | | | | | | | | | | | | | | another 16 bytes off of BTX (and thus boot2): - Compare against the value of %eax that is saved on the stack instead of loading it into %eax (which requires saving the current %eax on the stack). - Use %ch to examine the keyboard flag state in the BIOS to see if Ctrl-Alt-Del is pressed instead of %al so we don't have to save %eax on the stack anymore.

| | | | | | | | | | | | | | | | | | | | BTX (and thus boot2): - Don't bother saving %eax, %ebx, or %ecx as it is not necessary. - Use a more compact sequence to load the base value out of a GDT entry by loading the contiguous low 24 bits into the upper 24 bits of %eax, loading the high 8 bits into %al, and using a ror to rotate the bits (2 mov's and a ror) rather than loading the pieces in smaller chunks (3 mov's and a shl). - Use movzwl + leal instead of movl + movw + shll + addl. - Use 'xchgl %eax,%foo' rather than 'movl %eax,%foo' for cases where it's ok to trash %eax. xchgl %eax, foo is a 1-byte opcode whereas the mov is a 2-byte opcode. - Use movzwl rather than xorl + movw.
