To help support this, we add SHARED_FIELD_XX macros that create SHIFT, LENGTH, and MASK macros for the fields that are shared across registers, and accessors for these fields. An example use may look as follows: There is a peripheral with registers REG_MODE1 and REG_MODE2 at different addreses, and both have a field FIELD1 initialized by SHARED_FIELD(). Depending on what mode the peripheral is operating in, the user could extract FIELD1 via SHARED_ARRAY_FIELD_EX32(s->regs, R_REG_MODE1, FIELD1) or SHARED_ARRAY_FIELD_EX32(s->regs, R_REG_MODE2, FIELD1) Signed-off-by: Joe Komlodi <komlodi@google.com> Change-Id: Id3dc53e7d2f8741c95697cbae69a81bb699fa3cb Message-Id: <20220331043248.2237838-2-komlodi@google.com> Signed-off-by: Cédric Le Goater <clg@kaod.org> --- include/hw/registerfields.h | 70 +++++++++++++++++++++++++++++++++++++ 1 file changed, 70 insertions(+) diff --git a/include/hw/registerfields.h b/include/hw/registerfields.h index XXXXXXX..XXXXXXX 100644 --- a/include/hw/registerfields.h +++ b/include/hw/registerfields.h @@ -XXX,XX +XXX,XX @@ #define ARRAY_FIELD_DP64(regs, reg, field, val) \ (regs)[R_ ## reg] = FIELD_DP64((regs)[R_ ## reg], reg, field, val); + +/* + * These macros can be used for defining and extracting fields that have the + * same bit position across multiple registers. + */ + +/* Define shared SHIFT, LENGTH, and MASK constants */ +#define SHARED_FIELD(name, shift, length) \ + enum { name ## _ ## SHIFT = (shift)}; \ + enum { name ## _ ## LENGTH = (length)}; \ + enum { name ## _ ## MASK = MAKE_64BIT_MASK(shift, length)}; + +/* Extract a shared field */ +#define SHARED_FIELD_EX8(storage, field) \ + extract8((storage), field ## _SHIFT, field ## _LENGTH) + +#define SHARED_FIELD_EX16(storage, field) \ + extract16((storage), field ## _SHIFT, field ## _LENGTH) + +#define SHARED_FIELD_EX32(storage, field) \ + extract32((storage), field ## _SHIFT, field ## _LENGTH) + +#define SHARED_FIELD_EX64(storage, field) \ + extract64((storage), field ## _SHIFT, field ## _LENGTH) + +/* Extract a shared field from a register array */ +#define SHARED_ARRAY_FIELD_EX32(regs, offset, field) \ + SHARED_FIELD_EX32((regs)[(offset)], field) +#define SHARED_ARRAY_FIELD_EX64(regs, offset, field) \ + SHARED_FIELD_EX64((regs)[(offset)], field) + +/* Deposit a shared field */ +#define SHARED_FIELD_DP8(storage, field, val) ({ \ + struct { \ + unsigned int v:field ## _LENGTH; \ + } _v = { .v = val }; \ + uint8_t _d; \ + _d = deposit32((storage), field ## _SHIFT, field ## _LENGTH, _v.v); \ + _d; }) + +#define SHARED_FIELD_DP16(storage, field, val) ({ \ + struct { \ + unsigned int v:field ## _LENGTH; \ + } _v = { .v = val }; \ + uint16_t _d; \ + _d = deposit32((storage), field ## _SHIFT, field ## _LENGTH, _v.v); \ + _d; }) + +#define SHARED_FIELD_DP32(storage, field, val) ({ \ + struct { \ + unsigned int v:field ## _LENGTH; \ + } _v = { .v = val }; \ + uint32_t _d; \ + _d = deposit32((storage), field ## _SHIFT, field ## _LENGTH, _v.v); \ + _d; }) + +#define SHARED_FIELD_DP64(storage, field, val) ({ \ + struct { \ + uint64_t v:field ## _LENGTH; \ + } _v = { .v = val }; \ + uint64_t _d; \ + _d = deposit64((storage), field ## _SHIFT, field ## _LENGTH, _v.v); \ + _d; }) + +/* Deposit a shared field to a register array */ +#define SHARED_ARRAY_FIELD_DP32(regs, offset, field, val) \ + (regs)[(offset)] = SHARED_FIELD_DP32((regs)[(offset)], field, val); +#define SHARED_ARRAY_FIELD_DP64(regs, offset, field, val) \ + (regs)[(offset)] = SHARED_FIELD_DP64((regs)[(offset)], field, val); + #endif -- 2.35.3 From: Joe Komlodi <komlodi@google.com> This cleans up some of the field accessing, setting, and clearing bitwise operations, and wraps them in macros instead.

As part of this, we also do additional cleanup to use ARRAY_FIELD_ macros instead of FIELD_ macros on registers.

} static void aspeed_2400_i2c_class_init(ObjectClass *klass, void *data) -- 2.35.3 From: Joe Komlodi <komlodi@google.com> On AST2600, I2C has a secondary mode, called "new mode", which changes the layout of registers, adds some minor behavior changes, and introduces a new way to transfer data called "packet mode". Most of the bit positions of the fields are the same between old and new mode, so we use SHARED_FIELD_XX macros to reuse most of the code between the different modes. For packet mode, most of the command behavior is the same compared to other modes, but there are some minor changes to how interrupts are handled compared to other modes.

However, the default fmc flash model of ast1030-a1 EVB is "w25q80bl" whose size is 1MB. To test SoC flash models, introduces a new page_addr member in TestData structure, so users can set the offset for flash page read/write command testing.
