-- gerrit commit 7c7cfd66344d96fd68e7d62fb52ef615296cad29 Author: Antonio Borneo <[email protected]> Date: Sun Aug 8 13:51:33 2021 +0200 jep106: use packed jedec manufacturer code JEP106 encodes JEDEC-assigned manufacture code as: a) a sequence of zero or more escape codes 0x7f; b) an odd-parity bit of the next 7 bits; c) 7 bits. The same code is often represented as a single value composed by the logical OR between: - the number of escape codes in a), shifted left by 7 positions; - the 7 bits in c). This is the preferred packed representation used by this change. Currently there are only two uses of JEP106 in openocd to get the manufacturer name: - to decode the JTAG IDCODE of each TAP, where the JEP106 code is already packed as in the preferred representation above in bits IDCODE[11:1]; - to decode the ARM CoreSight PIDR register, where the JEP106 code is split in 3 parts: = PIDR3[3:0], corresponding to bits [10:7] of the packed code; = PIDR2[2:0], corresponding to bits [6:4] of the packed code; = PIDR1[7:4], corresponding to bits [3:0] of the packed code. Wrap the existing JEP106 decode function in a simpler API using the packed code. Simplify the callers by skipping the bit unpacking. Change the manufacturer code in CoreSight table dap_partnums[] to match the packed representation, by removing the always-one bit 7 erroneously taken from PIDR bit JEDEC and included in the former table.
