* machine/rp2350: add flash support for rp2350
* combine duplicate files
* clean things up and group by source file
* add stubbed out xip cache clean func if needed in the future
* update flash_enable_xip_via_boot2
* remove unused macros and fix inconsistent formatting
* make flash size configurable like rp2040
* add missing flash size configs
* retain big Go CGo compatibility per #4103
* clarify CS0_SIZE source and remove single-use typedef
Don't block forever if there's nothing to receive. On the other hand,
process the entire FIFO, not just a single byte.
This fixes an issue where the rp2350 would hang after programming through
openocd, where the UART0 interrupt would be spuriously pending.
Right now it doesn't compile, with errors like the following:
# machine
/app/tinygo/src/machine/board_pico.go:7:13: undefined: GPIO0
/app/tinygo/src/machine/board_pico.go:8:13: undefined: GPIO1
/app/tinygo/src/machine/board_pico.go:9:13: undefined: GPIO2
/app/tinygo/src/machine/board_pico.go:10:13: undefined: GPIO3
[...etc...]
This patch should fix that.
* machine: add support for core voltage adjustments to rp2040
In preparation for bumping the core frequency of the rp2040, this
change implements the required core voltage adjustment logic.
* machine: bump rp2040 to 200MHz
Follow-up to #4728 which implemented the algorithm for finding the
dividers.
The calculation is computed at compile time by interp, as verified by
building example/blinky1 for -target pico.
We can't use the bytes package in Go 1.24 since it would result in an
import cycle. Therefore, use bytealg.Index instead.
(I'm not sure this code is correct - just searching for a range of bytes
seems brittle. But at least this commit shouldn't change the code).
* initial implementation for Tillitis TKey device
* add UART implementation for TKey
* add Pin interface implementation for TKey touch sensor
* add RNG interface implementation for TKey
* add helpful machine package functions to return identifiers such as name and version for TKey
* use built-in timer for sleep timing on TKey
* modify UART implementation for TKey to implement Serialer interface
* implement BLAKE2s ROM function call for TKey device
* handle abort by triggering TKey device fault using illegal instruction to halt CPU
* simplify TKey implementation by inheriting from existing riscv32 target
* return error for trying to configure invalid baudrates on UART
* add tkey to builder test
* be very specific for features passed to LLVM for specific config in use for TKey
* handle feedback items from TKey device code review

TODO: Remove the go.mod/go.sum in internal/tools once doing so doesn't break CI (e.g. once we drop support for go 1.19)
* builder/cc1as.h: fix typo found by 'make spell'
* GNUmakefile: remove exception for inbetween, fix instance now found by 'make spell'
* GNUmakefile: remove exception for programmmer, fix instance now found by 'make spell'
* go.mod: use updated misspell. GNUmakefile: add spellfix target, use it.
* ignore directories properly when invoking spellchecker.
* make spell: give internal/tools its own go.mod, as misspell requires newer go
* make lint: depend on tools and run the installed revive
(which was perhaps implied by the change that added revive to internal/tools,
but not required in GNUmakefile until we gave internal/tools its own temporary go.mod)
* .github: now that 'make spell' works well, run it from CI
* GNUmakefile: make spell now aborts if it finds misspelt words, so what it finds doesn't get lost in CI logs
* GNUmakefile: tools: avoid -C option on go generate to make test-llvm15-go119 circleci job happy, see
https://cs.opensource.google/go/go/+/2af48cbb7d85e5fdc635e75b99f949010c607786
* internal/tools/go.mod: fix format of go version to leave out patchlevel, else go complains.
