01r,25aug05,dlk  Support .text.init, .text.fast, .data.init, .data.fast.
01r,29jul05,slk  SPR 104264: fix MIPS romResident images
01q,06may05,rlg  changes for MIPS specific devices
01p,03jul04,f_b  Improved support for data alignment
01o,12dec03,sn   added more .rodata.str1.* handlers
01n,04dec03,sn   Diab: .rodata.* is not handled correctly by Diab linker; instead
		 use specific names
01m,28oct03,sn   Diab: collapse .rodata.cst* sections into .rodata
01l,29may02,tpw  Diab: pad out sections, needed for MIPS byteswap. SPR 78076
01k,24apr02,sn   GNU: SPR 75835 - added support for relocatable script link.OUT
01j,19apr02,tpw  Diab: provide _etext for ColdFire. SPR 75122
01i,06feb02,sn   Both: place .got2 to handle tramp.o (_x_gnu_tramp.o).
01h,25jan02,tpw  GNU: give debug sections explicit 0 addresses.
01g,14jan02,tpw  Diab: place .eh_frame data, in case of insistent GNU objects.
01f,14dec01,tpw  Diab: provide both underscore options of wrs_kernel* here too.
01e,05dec01,tpw  Both: Add .boot and .reset section support, for PPC 4xx series
                 and Book E.
01d,05dec01,tpw  Diab: Add .frame_info section to text region.
01c,03dec01,jab  Diab: replaced LOAD() with AT()
01b,14nov01,tpw  ALL: Correct some more bootrom/kernel issues.
01b,06nov01,tpw  GNU: Add /DISCARD/ directive to discard uninteresting sections
01a,01nov01,tpw  gnu script written
01a,29oct01,jab  diab script written
