2020-06-03icebox: Add support for the bit 1 of SHIFTREG_DIV_MODE on UP5kSylvain Munaut
This allows selection of the div-by-5 mode of the PLL. This bit can't be fuzzed because it's not supported by the lattice tools at all ... This only works for sure on the UP5k. I tested HX8k and it didn't support it, so I'm only adding this on the known working FPGA. Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
2020-05-28icetime: avoid string + int Clang warningEd Maste
Clang warns that "adding 'int' to a string does not append to the string". Although a false positive it's trivially avoided by using the array index equivalent &PREFIX[1].

This allows us to flash binaries at offsets that are smaller multiples.
2019-12-31Add iteration over list of frequencies for best solutionMats Engstrom
This patch adds support for icepll to try multiple input frequencies to find the best crystal for the desired output frequency. The values tested comes either from a specified file using-B, or from a default set of frequencies from Mousers "normally stocked" crystal oscillators.

2019-12-08icepack: Fix Windows-only stack overflow in CRAM pbm generation (fixes #241)The6P4C
On Windows, attempting to generate a netpbm image of the CRAM with `icepack -b` causes the tool to crash after writing only the netpbm header due to a stack overflow. The bug did not appear on Linux. This was traced to a large stack-allocated variable length array (`tile_type`) inside `FpgaConfig::write_cram_pbm`. For an 8k ice40 with 4 banks, `cram_width = 872` and `cram_height = 272` the `tile_type` array ends up at `4 * 872 * 272 * sizeof(uint32_t) =` 3794944 bytes, or about 3.6 MiB. The fix replaces the large stack VLA with an array of 4 (bank) 2D C++ vectors, moving the large amount of data to the heap. Even though the fix is not in a Windows-specific code path (and hence applies to all platforms), I think it's wise to eliminate such a large stack allocation entirely. The fix has been tested working on both Windows and an Ubuntu WSL install.
