2019-04-10libpayload: Deduplicate strtol and strtoullJulius Werner
Our strtol() and strtoull() function contain almost exactly the same code. This is a) bad in general and b) may cause the code to get out of sync, such as it recently happened with CB:32029. This patch changes strtol() to be based on strtoull() so that the main parsing code exists only once, and also adds a strtoll() to round off the library. Also fix the bounds imposed by strtoul() to be based on the actual length of a 'long', not hardcoded to 32-bits (which is not equivalent on all architectures).

2019-04-10libpayload: limits.h: Provide reliable definitions for all XXX_MAX/MINJulius Werner
Our current limits.h only provides (U)INT_MAX constants. This patch adds most others expected by POSIX. Since some of these may be different depending on architecture (e.g. 'long' is 32-bit on x86 and 64-bit on arm64), provide a definition that will automatically figure out the right value for the data model the compiler is using (as long as it's using two's complement for signed integers, which I think we can assume these days).

2019-04-10libpayload: Fix CONFIG_LP_DEBUG_MALLOC for 64-bit archsJulius Werner
New compilers are a little more stringent about defining the same prototype more than once, so some of our CONFIG_LP_DEBUG_MALLOC wrappers don't quite work the way they are written anymore. Also, several of the printf()s weren't written 64-bit safe. And let's add some double-evaluation safety while I'm here anyway... and I have no idea why this ever depended on CONFIG_LP_USB, that just seems like a typo.

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.

2018-10-12libpayload: arm64: Make exception handling closer to arm32Julius Werner
This patch reworks the arm64 exception handling to be more similar to how it works on arm32. This includes a bunch of features like actually saving and restoring more exception state in the exception_state structure and supporting the same sort of partial reentrancy that is useful for GDB. Since there's no instruction to directly load into or store out of SP on arm64, we can't do quite the same thing where we use that to read an exception_state_ptr variable right after exception entry when no other register is available. But we can do something very similar by (ab-)using the "high" stack pointer (SP_EL2) as a pointer to the exception_state struct and providing a function to change it.

2018-10-12libpayload: arm64: Conform to new coreboot lib_helpers.h and assume EL2Julius Werner
This patch adds the new, faster architectural register accessors to libpayload that were already added to coreboot in CB:27881. It also hardcodes the assumption that coreboot payloads run at EL2, which has already been hardcoded in coreboot with CB:27880 (see rationale there). This means we can drop all the read_current/write_current stuff which added a lot of unnecessary helpers to check the current exception level. This patch breaks payloads that used read_current/write_current accessors, but it seems unlikely that many payloads deal with this stuff anyway, and it should be a trivial fix (just replace them with the respective _el2 versions). Also add accessors for a couple of more registers that are required to enable debug mode while I'm here.

2018-04-19libpayload: Move GDB functions to stdlib.hJulius Werner
When GDB support is compiled in, halt() in libpayload will call gdb_enter(). halt() is defined in <stdlib.h> and gdb_enter() in <libpayload.h>. Usually files just include <libpayload.h> so this is not a problem, but in some situatons a payload may just include <stdlib.h> (or a file including it like <assert.h>), leading to an undeclared identifier here. Move the GDB functions to <stdlib.h> to solve this.

2018-03-23arch/arm64/armv8/mmu: Add support for 48bit VAPatrick Rudolph
The VA space needs to be extended to support 48bit, as on Cavium SoCs the MMIO starts at 1 << 47. The following changes were done to coreboot and libpayload: * Use page table lvl 0 * Increase VA bits to 48 * Enable 256TB in MMU controller * Add additional asserts Tested on Cavium SoC and two ARM64 Chromebooks.

2017-11-06endian: Fix bebitenc() to actually encode big-endianJulius Werner
bebitenc() just runs a downward loop over the same body as lebitenc(). That doesn't give you a byte-swapped result, it gives you the same final value, just starting from the other side to fill it in. (Also, it confused i++ and i--, so it really gives you a compiler error.) The correct code needs to have the array index inverted relative to the bit shift index to produce a big endian result.
