397d7d5a1b arm: config: enforce -fno-pic for gcc
Android's tool chain enable the -mandroid at default.
This option will enable the -fpic, which cause uboot compilation
failure:
"
 LD      u-boot
 u-boot contains unexpected relocations: R_ARM_ABS32
 R_ARM_RELATIVE
"

In my testcase, arm-linux-androideabi-gcc-4.9 internally
enables '-fpic', so when compiling code, there will be
relocation entries using type R_ARM_GOT_BREL and .got
section. When linking all the built-in.o using ld, there
will be R_ARM_ABS32 relocation entry and .got section
in the final u-boot elf image. This can not be handled
by u-boot, since u-boot only expects R_ARM_RELATIVE
relocation entry.
arm-poky-linux-gnueabi-gcc-4.9 default does not enable '-fpic',
so there is not .got section and R_ARM_GOT_BREL in built-in.o.
And in the final u-boot elf image, all relocation entries are
R_ARM_RELATIVE.

we can pass '-fno-pic' to xxx-gcc to disable pic. whether
the toolchain internally enables or disables pic, '-fno-pic'
can work well.

c5e954eccd ARM: Disable "DISCARD" for secure section if CONFIG_ARMV7_SECURE_BASE isn't defined
"DISCARD" will remove ._secure.text relocate, but PSCI framework
has already used some absolute address those need to relocate.

Use readelf -t -r u-boot show us:
.__secure_start		addr: 601408e4
.__secure_end		addr: 60141460

60141140  00000017 R_ARM_RELATIVE

6014145c  00000017 R_ARM_RELATIVE
202	ldr     r5, =psci_text_end

Solutions:
1. Change absolute address to RelAdr.
   Based on LDR (immediate, ARM), we only have 4K offset to jump.
Now PSCI code size is close to 4K size that is LDR limit jump size,
so even if the LDR is based on the current instruction address,
there is also have a risk for RelAdr. If we use two jump steps I
think we can fix this issue, but looks too hack, so give up this way.

2. Enable "DISCARD" only for CONFIG_ARMV7_SECURE_BASE has defined.
   If CONFIG_ARMV7_SECURE_BASE is defined in platform, all of secure
will in the BASE address that is absolute.

a592e6fb7f arm: Replace test for CONFIG_ARMV7 with CONFIG_CPU_V7
The arch/arm/lib/cache-cp15.c checks for CONFIG_ARMV7 and if this macro is
set, it configures TTBR0 register. This register must be configured for the
cache on ARMv7 to operate correctly.

The problem is that noone actually sets the CONFIG_ARMV7 macro and thus the
TTBR0 is not configured at all. On SoCFPGA, this produces all sorts of minor
issues which are hard to replicate, for example certain USB sticks are not
detected or QSPI NOR sometimes fails to write pages completely.

The solution is to replace CONFIG_ARMV7 test with CONFIG_CPU_V7 one. This is
correct because the code which added the test(s) for CONFIG_ARMV7 was added
shortly after CONFIG_ARMV7 was replaced by CONFIG_CPU_V7 and this code was
not adjusted correctly to reflect that change.

a29b012037 video: Add a console driver that uses TrueType fonts
The existing 8x16 font is adequate for most purposes. It is small and fast.
However for boot screens where information must be presented to the user,
the console font is not ideal. Common requirements are larger and
better-looking fonts.

This console driver can use TrueType fonts built into U-Boot, and render
them at any size. This can be used in scripts to place text as needed on
the display.

This driver is not really designed to operate with the command line. Much
of U-Boot expects a fixed-width font. But to keep things working correctly,
rudimentary support for the console is provided. The main missing feature is
support for command-line editing.

testing. If the boardenv doesn't specify a set of sizes, the built-in list

56382a81f3 test/py: make net test aware of USB and PCI enumeration
The existing net test executes a list of commands supplied by boardenv
variable env__net_pre_commands. The idea was that boardenv would know
whether the Ethernet device was attached to USB, PCI, ... and hence was
the best place to put any commands required to probe the device.

However, this approach doesn't scale well when attempting to use a single
boardenv across multiple branches of U-Boot, some of which require "pci
enum" to enumerate PCI and others of which don't, or don't /yet/ simply
because various upstream changes haven't been merged down.

This patch updates the test to require that the boardenv state which HW
features are required for Ethernet to work, and lets the test itself map
that knowledge to the set of commands to execute. Since this mapping is
part of the test script, which is part of the U-Boot code/branch, this
approach is more scalable. It also feels cleaner, since again boardenv
is only providing data, rather than test logic.

3483b75d94 distro bootcmd: make net boot only optionally start USB
Currently, the distro boot commands always enumerate USB devices before
performing network operations. However, depending on the board and end-
user configuration, network devices may not be attached to USB, and so
enumerating USB may not be necessary. Enhance the scripts to make this
step optional, so that the user can decrease boot time if they don't
need USB.

This change is performed by moving the "usb start" invocation into a
standalone variable. If the user desires, they can replace that
variable's value with some no-op command such as "true" instead.

Booting from a USB storage device always needs to enumerate USB devices,
so this action is still hard-coded.

e578b92cdb Implement "pci enum" command for CONFIG_DM_PCI
With CONFIG_DM_PCI enabled, PCI buses are not enumerated at boot, as they
are without that config option enabled. No command exists to enumerate the
PCI buses. Hence, unless some board-specific code causes PCI enumeration,
PCI-based Ethernet devices are not detected, and network access is not
available.

This patch implements "pci enum" in the CONFIG_DM_PCI case, thus giving a
mechanism whereby PCI can be enumerated.

do_pci()'s handling of case 'e' is moved into a single location before the
dev variable is assigned, in order to skip calculation of dev. The enum
sub-command doesn't need the dev value, and skipping its calculation
avoids an irrelevant error being printed.

Using a command to initialize PCI like this has a disadvantage relative to
enumerating PCI at boot. In particular, Ethernet devices are not probed
during PCI enumeration, but only when used. This defers setting variables
such as ethact, ethaddr, etc. until the first network-related command is
executed. Hopefully this will not cause further issues. Perhaps in the
long term, we need a "net start/enum" command too?

be1df82656 test/py: dfu: error out if USB device already exists
The DFU test requests U-Boot configure its USB controller in device mode,
then waits for the host machine to enumerate the USB device and create a
device node for it. However, this wait can be fooled if the USB device
node already exists before the test starts, e.g. if some previous software
stack already configured the USB controller into device mode and never
de-configured it. This "previous software stack" could even be another
test/py test, if U-Boot's own USB teardown does not operate correctly. If
this happens, dfu-util may be run before U-Boot is ready to serve DFU
commands, which may cause false test failures.

Enhance the dfu test to fail if the device node exists before it is
expected to.

dd8204de15 ARM: tegra: shut down USB device controller at boot
When loading U-Boot into RAM over USB protocols using tools such as
tegrarcm or L4T's exec-uboot.sh/tegraflash.py, Tegra's USB device
mode controller is initialized and enumerated by the host PC running
the tool. Unfortunately, these tools do not shut down the USB
controller before executing the downloaded code, and so the host PC
does not "de-enumerate" the USB device. This patch implements optional
code to shut down the USB controller when U-Boot boots to avoid leaving
a stale USB device present.

e787a58fe2 test/py: make crash detection more robust
test/py contains logic to detect the target crashing and rebooting by
searching the console output for a U-Boot signon message, which will
presumably be emitted when the system boots after the crash/reset.

Currently, this logic only searches for the exact signon message that
was printed by the U-Boot version under test, upon the assumption that
binary is written into flash, and hence will be the version booted after
any reset. However, this is not a valid assumption; some test setups
download the U-Boot-under-test into RAM and boot it from there, and in
such a scenario an arbitrary U-Boot version may be located in flash and
hence run after any reset.

Fix the reset detection logic to match any U-Boot signon message. This
prevents false negatives.
