Roger Quadros [Wed, 24 Aug 2016 12:35:50 +0000 (15:35 +0300)]
board: am335x-icev2: add ethernet phy mode detection logic

Both ethernet ports can be used as CPSW ethernet (RMII mode)
or PRU ethernet (MII mode) by setting the jumper near the port.
Read the jumper value and set the pinmux, external mux and
PHY clock accordingly.

As jumper line is overridden by PHY RX_DV pin immediately
after bootstrap (power-up/reset), we have to use GPIO edge
detection to capture the jumper line status.

As u-boot doesn't provide any infrastructure for GPIO edge
detection, we directly access the GPIO registers.

Simon Glass [Thu, 6 Oct 2016 02:42:09 +0000 (20:42 -0600)]
Revert "x86: broadwell: gpio: Remove the codes to set up pin control"

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.

ARM: tegra: reduce DRAM size mapped into MMU on ARM64

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.

8 years agokbuild: generate u-boot.cfg as a byproduct of include/autoconf.mk
Masahiro Yamada [Mon, 26 Sep 2016 04:05:01 +0000 (13:05 +0900)]
kbuild: generate u-boot.cfg as a byproduct of include/autoconf.mk

Our build system still parses ad-hoc CONFIG options in header files
and generates include/autoconf.mk so that Makefiles can reference
them.  This gimmick was introduced in the pre-Kconfig days and will
be kept until Kconfig migration is completed.

The include/autoconf.mk is generated like follows:

  [1] Preprocess include/common.h with -DDO_DEPS_ONLY and
      retrieve macros into include/autoconf.mk.tmp
  [2] Reformat include/autoconf.mk.dep into include/autoconf.mk
      with tools/scripts/define2mk.sed script
  [3] Remove include/autoconf.mk.tmp

Here, include/autoconf.mk.tmp is similar to u-boot.cfg, which is
also generated by preprocessing include/config.h with -DDO_DEPS_ONLY.
In other words, there is much overlap among include/autoconf.mk and
u-boot.cfg build rules.

So, the idea is to split the build rule of include/autoconf.mk
into two stages.  The first preprocesses headers into u-boot.cfg.
The second parses the u-boot.cfg into include/autoconf.mk.  The
build rules of u-boot.cfg in Makefile and spl/Makefile will be gone.
