  riscv: dts: microchip: Use 'local-mac-address' for emac1
  riscv: Ensure the value of FP registers in the core dump file is up to date

U-Boot expects this alias to be in place in order to fix up the mac
address of the ethernet node.

Note on the Icicle Kit board, currently only emac1 is enabled so it
becomes the 'ethernet0'.

Per the DT spec, 'local-mac-address' is used to specify MAC address
that was assigned to the network device, while 'mac-address' is used
to specify the MAC address that was last used by the boot program,
and shall be used only if the value differs from 'local-mac-address'
property value.

The value of FP registers in the core dump file comes from the
thread.fstate. However, kernel saves the FP registers to the thread.fstate
only before scheduling out the process. If no process switch happens
during the exception handling process, kernel will not have a chance to
save the latest value of FP registers to thread.fstate. It will cause the
value of FP registers in the core dump file may be incorrect. To solve this
problem, this patch force lets kernel save the FP register into the
thread.fstate if the target task_struct equals the current.

 - fix the sifive-l2-cache device tree bindings for json-schema
   compatibility. This does not change the intended behavior of the
   binding.

 - avoid improperly freeing necessary resources during early boot.

  riscv: Fix a number of free'd resources in init_resources()
  dt-bindings: sifive-l2-cache: Fix 'select' matching

Function init_resources() allocates a boot memory block to hold an array of
resources which it adds to iomem_resource. The array is filled in from its
end and the function then attempts to free any unused memory at the
beginning. The problem is that size of the unused memory is incorrectly
calculated and this can result in releasing memory which is in use by
active resources. Their data then gets corrupted later when the memory is
reused by a different part of the system.

Fix the size of the released memory to correctly match the number of unused
resource entries.

 - a comment fix

  riscv: Fix comment regarding kernel mapping overlapping with IS_ERR_VALUE
  riscv: kexec: do not add '-mno-relax' flag if compiler doesn't support it

The current comment states that we check if the 64-bit kernel mapping
overlaps with the last 4K of the address space that is reserved to
error values in create_kernel_page_table, which is not the case since it
is done in setup_vm. But anyway, remove the reference to any function
and simply note that in 64-bit kernel, the check should be done as soon
as the kernel mapping base address is known.
