2016-10-11sandbox/fs: Use correct size path name bufferStefan Brüns
The readdir linux manpage explicitly states (quoting POSIX.1) that sizeof(d_name) is not correct for determining the required size, but to always use strlen. Grow the buffer if needed. Signed-off-by: Stefan Brüns <stefan.bruens@rwth-aachen.de> Acked-by: Simon Glass <sjg@chromium.org>
2016-10-11sandbox/fs: Make linking of nodes in os_dirent_ls more obviousStefan Brüns
Previously, after reading/creating the second dirent, the second entry would be chained to the first entry and the first entry would be linked to head. Instead, immediately link the first entry to head. Signed-off-by: Stefan Brüns <stefan.bruens@rwth-aachen.de> Acked-by: Simon Glass <sjg@chromium.org>

2016-10-11Revert "x86: broadwell: gpio: Remove the codes to set up pin control"Simon Glass
This makes the assumption that setting up pinctrl in cpu_init_r() is safe. On samus we need GPIOs before relocation in order to support power control. This commit fixes the following message on boot: initcall sequence ffe5c6f4 failed at call ffe01d3d (err=-1) ### ERROR ### Please RESET the board ### In any case it seems better to leave init to driver model, so that it can pick up the GPIO driver when it needs it. Since pinctrl is a dependency of the GPIO driver, we may as well put the dependency there and avoid these problems. This reverts commit 9769e05bcf79939bad23a719982dd1f85a110f3c.

2016-10-10ARM: tegra: reduce DRAM size mapped into MMU on ARM64Stephen Warren
ARM CPUs can architecturally (speculatively) prefetch completely arbitrary normal memory locations, as defined by the current translation tables. The current MMU configuration for 64-bit Tegras maps an extremely large range of addresses as DRAM, well beyond the actual physical maximum DRAM window, even though U-Boot only needs access to the first 2GB of DRAM; the Tegra port of U-Boot deliberately limits itself to 2GB of RAM since some HW modules on at least some 64-bit Tegra SoCs can only access a 32-bit physical address space. This change reduces the amount of RAM mapped via the MMU to disallow the CPU from ever speculatively accessing RAM that U-Boot will definitely not access. This avoids the possibility of the HW raising SError due to accesses to always-invalid physical addresses.
