We should re-check if the current use of _end; excluding the linker
scripts, I see these uses:
arch/powerpc/cpu/74xx_7xx/start.S: GOT_ENTRY(_end)
arch/powerpc/cpu/74xx_7xx/start.S: lwz r4,GOT(_end)
arch/powerpc/cpu/mpc512x/start.S: GOT_ENTRY(_end)

arch/powerpc/cpu/mpc5xx/start.S: lwz r4,GOT(_end)
arch/powerpc/cpu/mpc5xxx/start.S: GOT_ENTRY(_end)
arch/powerpc/cpu/mpc5xxx/start.S: lwz r4,GOT(_end)
arch/powerpc/cpu/mpc8220/start.S: GOT_ENTRY(_end)
arch/powerpc/cpu/mpc8220/start.S: lwz r4,GOT(_end)
arch/powerpc/cpu/mpc824x/start.S: GOT_ENTRY(_end)
arch/powerpc/cpu/mpc824x/start.S: lwz r4,GOT(_end)
arch/powerpc/cpu/mpc8260/start.S: GOT_ENTRY(_end)
arch/powerpc/cpu/mpc8260/start.S: lwz r4,GOT(_end)
arch/powerpc/cpu/mpc83xx/start.S: GOT_ENTRY(_end)
arch/powerpc/cpu/mpc83xx/start.S: lwz r4,GOT(_end)
arch/powerpc/cpu/mpc85xx/start.S: GOT_ENTRY(_end)
arch/powerpc/cpu/mpc85xx/start.S: lwz r4,GOT(_end)
arch/powerpc/cpu/mpc86xx/start.S: GOT_ENTRY(_end)
arch/powerpc/cpu/mpc86xx/start.S: lwz r4,GOT(_end)
arch/powerpc/cpu/mpc8xx/start.S: GOT_ENTRY(_end)

arch/powerpc/cpu/ppc4xx/start.S: GOT_ENTRY(_end)

arch/arm/cpu/sa1100/start.S: .word _end - _start
arch/arm/cpu/armv7/start.S: .word _end - _start

arch/avr32/lib/board.c: (unsigned long)_data, (unsigned long)_end);
arch/avr32/lib/board.c: monitor_len = _end - _text;
arch/m68k/lib/board.c:extern ulong _end;
arch/m68k/lib/board.c: len = (ulong)&_end - CONFIG_SYS_MONITOR_BASE;
arch/microblaze/cpu/start.S: addi r4, r0, __end
arch/microblaze/cpu/start.S: rsub r4, r5, r4 /* size = __end -
__text_start */
arch/nios2/cpu/start.S: * and between __bss_start and _end.
arch/nios2/cpu/start.S: movhi r6, %hi(_end)
arch/nios2/cpu/start.S: ori r6, r6, %lo(_end)
board/mousse/u-boot.lds.ram: _end = . ;
board/mousse/u-boot.lds.rom: _end = . ;
examples/standalone/stubs.c:extern unsigned long __bss_start, _end;
examples/standalone/stubs.c: while (cp < (unsigned char *)&_end) {
As far as I can tell, arch/powerpc/lib/board.c ,
arch/avr32/lib/board.c and examples/standalone/stubs.c actually all
mean __bss_end, as well as all the start.S files, so this seems to be
consistently used at least.
