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.

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.

regtools/desc: convert v1 stmp description files to v2

2016-02-06T15:32:53+00:00

Conversion done using swiss_knife as follows:
./swiss_knife convert --author "Amaury Pouly" --version "2.4.0" desc/regs-stmp3XXX-v1.xml desc/regs-stmp3XXX.xml

regtools: update v2 specification, library and tools

2016-02-06T15:12:55+00:00

A v2 register description file can now include register variants and instances
addresses can now be a list (previously it could only be a stride or a formula).
Update the library to deal with that. The convert option of swiss_knife was
updated and one incompatible change was introduce: if a v1 device has several
addresses, those are converted to a single v2 instance with list (instead of
several single instances). This should have been the behaviour from the start.
Swiss_knife can now also convert regdumps, in which case it needs to be given
both the dump and register description file. Also introduce two register
descriptions files (vsoc1000 and vsoc2000) which give more complicated examples
of v2 register description files.
