| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Board consists of SoM with stm32mp157c with 4G eMMC and 512M DDR3 RAM. Carrier board features USB and ETH interfaces and SD card connector. USB and ETH interfaces not yet operational. Boot from eMMC requires boot ack bit set.

| * | kvx: exclude dtb from malloc zoneClement Leger2020-08-111-2/+41
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | When dtb is provided by the FSBL (first stage bootloader), it might end up in the malloc zone initialized by barebox. While the dtb is discarded after being unflatten, if the dtb is provided right after barebox elf, then the malloc can overwrite it while unflattening it when allocating nodes. To avoid that, exclude the dtb from the malloc zone by checking if it overlaps it. If so, determine the largest zone for the allocation and modify the memory area to use that.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the TF-A is configured to have some output on the UART it does not set up the UART on its own, but just expects a pre-existing configuration. If Barebox did not set up the UART in the !DEBUG_LL case, TF-A will just hang without any user accessible debug output, which is a very non-obvious failure, so better be safe and always set up the UART in case TF-A wants to use it.

| * arm: module: Allow modules outside of bl rangeDavid Dgien2020-07-018-6/+295
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unlike the Linux kernel, barebox does not have a dedicated heap for storing modules. Therefore, if the system memory configuration places the general heap further away than can be reached by a 'bl' instruction (24 bits of address, or 16 MiB), then the module relocations will fail due to being out of range. Allocate PLTs when loading modules so that jumps and calls whose targets are too far away for their relative offsets to be encoded in the instructions themselves can be bounced via veneers in the module's PLT. The modules will use slightly more memory, but after rounding up to page size, the actual memory footprint is usually the same.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While we typically want to reuse as much barebox functionality as possible in sandbox, using system malloc(3) instead can be very useful when using external memory integrity tools. This is even useful for AddressSanitizer, because the reports resulting from the memory poisoning API are less detailed than the built-in support for the libc malloc(3). Note that a barebox "heap" is still allocated upfront. It's only used for request_sdram_region now though. Whatever is allocated by means of malloc and memalign will be ina disjunct heap.
