2016-05-25	regtools: add headergen_v2	Amaury Pouly	1	-11/+20
	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.

2016-04-08	regtools: add register access to soc desc	Amaury Pouly	1	-0/+6
	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.

2016-02-06	regtools: update v2 specification, library and tools	Amaury Pouly	1	-0/+396
	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. Change-Id: Id9415b8363269ffaf9216abfc6dd1bd1adbfcf8d
