From: Jonas Norling Date: Tue, 17 Oct 2017 06:57:06 +0000 (+0200) Subject: efm32: Refactor EFM32 chip family data, add more chips X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=6d390e1b2a393505b38e1d0fcd741cd0b1cf92aa;p=openocd efm32: Refactor EFM32 chip family data, add more chips Add support for more EFM32/EFR32 Series 1 families. The family IDs come from the DEVICE_FAMILY list in the EFM32GG11 reference manual, which is the most up to date source I could find. Register locations have been checked against SiLab's header files. No datasheets or headers were available for EFR32MG2, EFR32xG14 and EFM32TG11B, so they are just assumed to follow the pattern. EFM32GG11B has the MSC registers on a different address compared to other chips. This commit attempts not to change current behavior when detecting chips. One detail that has changed is that PAGE_SIZE is read before applying the workaround for old Giant and Leopard Gecko revisions, but this is believed to be OK because the register exists but just has an invalid value in it. The manuals disagree on which of 120 and 121 is WG, so this commit leaves it as is.
