regtools: add headergen_v2

2016-05-24T23:11:07+00:00

This new header generator works differently from the previous one:
- it uses the new format
- the generated macro follow a different style (see below)
- the generated macro are highly documented!
- it supports SCT-style platform or RMW-style ones

Compared to the old style, the new one generate a big set of macros per
register/field/enum (loosely related to iohw.h from Embedded C spec). The user
then calls generic (names are customizable) macros to perform operations:

reg_read(REG_A)
reg_read(REG_B(3))
reg_read_field(REG_A, FIELD_X)
reg_read_field(REG_B(3), COOL_FIELD)
reg_write(REG_A, 0x42)
reg_write_field(REG_A, FIELD_X(1), FIELD_Y(3), IRQ_V(FIQ))
reg_write_fielc(REG_B(3), COOL_FIELD_V(I_AM_COOL), BLA(42))

the following use RMW or SET/CLR variants, depending on target:
reg_set_field(REG_A, FLAG_U, FLAG_V)
reg_clr_field(REG_A, FIELD_X, FIELD_Y, IRQ)
reg_clr_field(REG_B(3), COOL_FIELD, BLA)

the following does clear followed by set, on SET/CLR targets:
reg_cs(REG_A, 0xff, 0x42)
reg_cs(REG_B(3), 0xaa, 0x55)
reg_cs_field(REG_A, FIELD_X(1), FIELD_Y(3), IRQ_V(FIQ))
reg_cs_field(REG_B(3), COOL_FIELD_V(I_AM_COOL))

The generator code is pretty long but has lots of documentation and lots of
macro names can be customized.

qeditor: port to the new hwstub library and add features

2016-04-08T17:46:46+00:00

This commit adds support for the version of the hwstub library, which requires
a lot of changes. It also adds some editing features, such as register access
and much better editing of fields using the mouse (double click on a field
to be able to resize and move it).

regtools: add register access to soc desc

2016-04-08T17:38:36+00:00

Registers (and variants) can now specify the type of access supported:
- unspecified: for variant means same as register, for register defaults R/W
- read/write
- read only
- write only
Backward compatibility is preserved by setting access to unspecified by default.

soc_desc: add default constructors to most structures

2016-04-08T16:06:27+00:00

After being caught by several bugs of the type "let's forgot to initialize
a field to default value", I'm finally fixing this.

regtools: Convert rk27xx register description file to v2 format

regtools: make description file parser stricter

2016-02-07T15:46:06+00:00

The parser would simply ignore unknown elements or attributes, which is bad
on many levels. Now any unknown tag will trigger a fatal error.
