kernel/arch/powerpc/boot/pseries-head.S, branch linux-4.3.yHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-4.3.y2014-04-28T07:36:21Zpowerpc/boot: Add support for 64bit little endian wrapper2014-04-28T07:36:21ZCédric Le Goaterclg@fr.ibm.com2014-04-24T07:23:39Zurn:sha1:147c05168fc86e824ccd1c0a02b40843e3cbca88
The code is only slightly modified : entry points now use the
FIXUP_ENDIAN trampoline to switch endian order. The 32bit wrapper
is kept for big endian kernels and 64bit is enforced for little
endian kernels with a PPC64_BOOT_WRAPPER config option.
The linker script is generated using the kernel preprocessor flags
to make use of the CONFIG_* definitions and the wrapper script is
modified to take into account the new elf64ppc format.
Finally, the zImage file is compiled as a position independent
executable (-pie) which makes it loadable at any address by the
firmware.

powerpc/boot: Add a global entry point for pseries2014-04-28T07:36:17ZCédric Le Goaterclg@fr.ibm.com2014-04-24T07:23:38Zurn:sha1:2d9afb369bc069f11a3a8696c4bdf95d4ddf1281
When entering the boot wrapper in little endian, we will need to fix
the endian order using a fixup trampoline like in the kernel. This
patch overrides the _zimage_start entry point for this purpose.
