- add new kernel memory layouts for MMUv3 cores: with 256MB and 512MB
KSEG size, starting at physical address other than 0;
- make kernel load address configurable;
- clean up kernel memory layout macros;
- drop sysmem early allocator and switch to memblock;
- enable kmemleak and memory reservation from the device tree;
- wire up new syscalls: userfaultfd, membarrier, mlock2, copy_file_range,
preadv2 and pwritev2;
- add new platform: Cadence Configurable System Platform (CSP) and new
core variant for it: xt_lnx;
- rearrange CCOUNT calibration code, make most of it generic;
- improve machine reset code (XTFPGA now reboots reliably with MMUv3
cores);
- provide default memmap command line option for configurations without
device tree support;
- ISS fixes: simdisk is now capable of using highmem pages, panic
correctly terminates simulator.
