Exynos: clock: change mask bits as per peripheral

We have assumed and kept mask bits for divider and pre-divider
as 0xf and 0xff, respectively. But these mask bits change from
one peripheral to another, and hence, need to be specified in

ARC HS and ARC EM are new cores based on ARCv2 ISA which is binary
incompatible with ISAv1 (AKA ARCompact).

Significant difference between ISAv2 and v1 is implementation of
interrupt vector table.

In v1 it is implemented in the same way as on many other architectures -
as a special location where user may put whether code executed in place
(if machine word of space is enough) or jump to a full-scale interrupt
handler.

In v2 interrupt table is just an array of adresses of real interrupt
handlers. That requires a separate section for IVT that is not encoded
as code by assembler.

This change adds support for following cores:
 * ARC EM6 (simple 32-bit microcontroller without MMU)
 * ARC HS36 (advanced 32-bit microcontroller without MMU)
 * ARC HS38 (advanced 32-bit microcontroller with MMU)

As a part of ARC HS38 new version of MMU (v4) was introduced.

9 years agoIntroduce board_init_f_mem() to handle early memory layout
Simon Glass [Sat, 7 Feb 2015 18:51:34 +0000 (11:51 -0700)]
Introduce board_init_f_mem() to handle early memory layout

At present on some architectures we set up the following before calling
board_init_f():

   - global_data
   - stack
   - early malloc memory

Adding the code to support early malloc and global data setup to every
arch's assembler start-up is a pain. Also this code is not actually
architecture-specific. We can use common code for all architectures and
with a bit of care we can write this code in C.

Add a new function to deal with this. It should be called after memory
is available, with a pointer to the top of the area that should be used
before relocation. The function will set things up and return the lowest
memory address that it allocated/used. That can then be set as the top
of the stack.

Note that on some archs this function will use the stack, so the stack
pointer should be set to same value as is pased to board_init_f_mem().
A margin of 128 bytes will be left for this stack, so that it is not
overwritten. This means that 64 bytes is wasted by this early call.
This is not strictly necessary on several more modern archs, so we could
remove this at the cost of some arch-dependent code.

With this function there is no-longer any need for the assembler code to
zero global_data or set up the early malloc pointers.
