2019-04-04Make common macros double-evaluation safeJulius Werner
I just got hit by a double-evaluation bug again, it's time to attempt to fix this once more. Unfortunately there are several issues that don't make this easy: - bitfield variables don't support typeof() - local macro variables that shadow others trigger -Werror=shadow - sign warnings with integer literal and unsigned var in typeof-MIN() - ({ statement expressions }) can not be used outside functions - romcc doesn't support any of the fancy GCC/clang extensions This patch tries to address all of them as far as possible with macro magic. We don't have the technology to solve the bitfield and non-function context issues yet (__builtin_choose_expr() still throws a "no statement expression outside a function" error if it's only in the branch that's not chosen, unfortunately), so we'll have to provide alternative macros for use in those cases (and we'll avoid making __ALIGN_MASK() double-evaluation safe for now, since it would be annoying to do that there and having an alignment mask with side effects seems very unlikely). romcc can continue using unsafe versions since we're hopefully not writing a lot of new code for it. Sign warnings can be avoided in literal/variable comparisons by always using the type of the variable there. Shadowing is avoided by picking very explicit local variable names and using a special __COUNTER__ solution for MIN() and MAX() (the only ones of these you're likely to nest). Also add DIV_ROUND_UP() to libpayload since it's a generally quite useful thing to have.

2018-06-15util/cbfstool: Support FIT payloadsPatrick Rudolph
In order to support booting a GNU/Linux payload on non x86, the FIT format should be used, as it is the defacto standard on ARM. Due to greater complexity of FIT it is not converted to simple ELF format. Add support for autodecting FIT payloads and add them as new CBFS_TYPE 'fit'. The payload is included as is, with no special header. The code can determine the type at runtime using the CBFS_TYPE field. Support for parsing FIT payloads in coreboot is added in a follow on commit. Compression of FIT payloads is not supported, as the FIT sections might be compressed itself. Starting at this point a CBFS payload/ can be either of type FIT or SELF. Tested on Cavium SoC.
