in the makefile fragment. Using kernel.org 4.9 x86_64-linux-gcc
works out of the box, since it is preconfigured to generate 64-bit

When building for a TPL/SPL setup (e.g. on the RK3368), we need the
TPL stage to have the extra space for for the 'Rockchip SPL name'
(i.e. 'RK33' word). Yet, the SPL will start execution at its first
word (i.e. the first word in the SPL binary needs to be a valid
instruction). To make things a bit more involved, CONFIG_SPL_BUILD
is defined both for the SPL and the TPL stage.
To avoid having to explicitly test for the first stage (TPL, if and
only if TPL and SPL are built, SPL otherwise), this commit modifies
the sequence to repeat the 'b reset' (instead of reserving 4 bytes
of undefined space) at the start of the boot0 hook: if overwritten
(and execution starts at the second word), the first instruction is
still a 'b reset'... if not overwritten, we start on a 'b reset' as
well.
This solution wouldn't even require the check whether we are in the
SPL/TPL build (i.e. CONFIG_SPL_BUILD), but we leave this check in for
documentation purposes.

check for the return value in r0 according to regular ARM calling
conventions.
However, this assumption breaks down if the compiler inlines the
functions. The caller is then under no obligation to use r0 for the
result.
To fix this disconnect, we must explicitly move the return value

On early K2 devices (eg. K2HK) the secure ROM code does not support
loading secure code to firewall protected memory, before decrypting,
authenticating and executing it.
To load the boot monitor on these devices, it is necessary to first
authenticate and run a copy loop from non-secure memory that copies
the boot monitor behind firewall protected memory, before decrypting
and executing it.
On K2G, the secure ROM does not allow secure code executing from
unprotected memory. Further, ROM first copies the signed and encrypted
image into firewall protected memory, then decrypts, authenticates
and executes it.
As a result of this, we cannot use the copy loop for K2G. The
mon_install has to be modified to pass the address the signed and
encrypted secure boot monitor image to the authentication API.
For backward compatibility with other K2 devices and K2G GP,
the mon_install API still supports a single argument. In this case
the second argument is set to 0 by u-boot and is ignored by ROM

This converts the following to Kconfig:

CONFIG_ENV_IS_IN_NAND
CONFIG_ENV_IS_IN_UBI
CONFIG_ENV_IS_NOWHERE
In fact this already exists for sunxi as a 'choice' config. However not
all the choices are available in Kconfig yet so we cannot use that. It
would lead to more than one option being set.
In addition, one purpose of this series is to allow the environment to be
stored in more than one place. So the existing choice is converted to a
normal config allowing each option to be set independently.
There are not many opportunities for Kconfig updates to reduce the size of
this patch. This was tested with

U-Boot has up until now built with -fpic for the MIPS architecture,
producing position independent code which uses indirection through a
global offset table, making relocation fairly straightforward as it
simply involves patching up GOT entries.
Using -fpic does however have some downsides. The biggest of these is
that generated code is bloated in various ways. For example, function
calls are indirected through the GOT & the t9 register:
8f998064 lw t9,-32668(gp)
0320f809 jalr t9
Without -fpic the call is simply:
0f803f01 jal be00fc04 <puts>
This is more compact & faster (due to the lack of the load & the
dependency the jump has on its result). It is also easier to read &
debug because the disassembly shows what function is being called,
rather than just an offset from gp which would then have to be looked up
in the ELF to discover the target function.
Another disadvantage of -fpic is that each function begins with a
sequence to calculate the value of the gp register, for example:
3c1c0004 lui gp,0x4
279c3384 addiu gp,gp,13188
0399e021 addu gp,gp,t9
Without using -fpic this sequence no longer appears at the start of each
function, reducing code size considerably.
This patch switches U-Boot from building with -fpic to building with
-fno-pic, in order to gain the benefits described above. The cost of
this is an extra step during the build process to extract relocation
data from the ELF & write it into a new .rel section in a compact
format, plus the added complexity of dealing with multiple types of
relocation rather than the single type that applied to the GOT. The
benefit is smaller, cleaner, more debuggable code. The relocate_code()
function is reimplemented in C to handle the new relocation scheme,
which also makes it easier to read & debug.
Taking maltael_defconfig as an example the size of u-boot.bin built
using the Codescape MIPS 2016.05-06 toolchain (gcc 4.9.2, binutils
2.24.90) shrinks from 254KiB to 224KiB.

The Turris Omnia is a open-source router created by CZ.NIC.
The code is based on the Marvell/db-88f6820-gp by Stefan Roese
with modifications from Tomas Hlavacek in the CZ.NIC turris-omnia-uboot
repository, which can be found at
https://gitlab.labs.nic.cz/turris/turris-omnia-uboot
By default, the Turris Omnia uses btrfs as the main and only filesystem,
and also loads kernel and device tree from this filesystem. Since U-Boot
does not yet support btrfs, you should not flash your Turris Omnia board
with this unless you know what you are doing.

The declaration of otg*_plat and otg*_board_data is guarded by
CONFIG_USB_MUSB_*, but their use in arch_misc_init is not. The
ifdef flow goes something like:
if (CONFIG_USB_MUSB_* && other_conditions)
declare usb_data
if (other_conditions)
use usb_data
Thus when CONFIG_USB_MUSB_* is not declared, we try to use the
data structures, but these structures aren't defined.
To fix this, move the USB initialization code into the same #ifdef
which guards the declaration of the data structures. Since the DM_USB
vs legacy cases are completely different, use two versions of
arch_misc_init(), for readability.

This commit partially restores support for the 8xx, with the
following limitations:
- Restores support for MPC866 and MPC885 only
- Does not restore IDE, PCMCIA, I2C, USB
- Does not restore examples
- Does not restore POST
- Does not restore Ethernet on SCC
- Does not restore console on SCC
- Does not restore bedbug and kgdb support
As the 866 and 885 do not support the following features,
they are not restored either:
- VIDEO / LCD
- RTC clock
The CPM uCODE patch is not restored either, because:
- 866 and 885 already have support for I2C and SPI relocation
without a uCODE patch
- relocation of SMC, I2C or SPI is only needed for using SCCs
for Ethernet or QMC
The dynamic setup/calculation of clocks is removed, we
expect the target being use with the clock and PLPRCR register
defined in the configuration.
All the clock settings for 8xx prior to 866 is removed as
well as we now only support 866 and 885.
This code is mature and addresses mature boards. Therefore
all code enclosed in '#if 0/#endif' and '#if XX_DEBUG/#endif'
is unneeded.

In order to keep traceability of the changes, they will be

followup patch.
This patch also declares CSSI as point of contact for the update
of the 8xx platform, as those boards are the only ones still
being maintained on the 8xx area. A later patch will add
those boards to the tree.

AVR32 is gone. It's already more than two years for no support in Buildroot,
even longer there is no support in GCC (last version is heavily patched 4.2.4).
Linux kernel v4.12 got rid of it (and v4.11 didn't build successfully).
There is no good point to keep this support in U-Boot either.

* 4Gb of DDR (we use only lowest 1Gb out of it now)
* Lots of DesigWare peripherals
* Different connectivity modules:
- Synopsys HAPS HT3
- Arduino-compatible connector
- MikroBUS
This initial commit supports the following peripherals:
* UART (DW 8250)
* Ethernet (DW GMAC)
* SD/MMC (DW Mobile Storage)
* USB 1.1 & 2.0

We used to use the same memory layout and size for a couple of
boards and thus we just hardcoding IOC aperture start and size.
Now when we're getting more boards with more memory on board we
need to have an ability to set IOC so it matches real DDR layout
and size.
Even though it is not really a must but for simplicity we assume
IOC covers all the DDR we have, that gives us a chance to not
bother where DMA buffers are allocated - any part of DDR is OK.

ARCompact cores are not supposed to be used in SMP designs
(this doesn't stop people from creation of heterogeneous chips,
for an example keep reading) so there's no point in
checking ARCNUM and halting somebody if we build for ARC700.
Moreover on AXS101 board we have ARC770 in the ASIC together with
other ARC cores and ARC770 happens to be the last node in JTAG chain
with ARCNUM = 4. And existing check halts the one and only core we
want keep running.

When enabling both SDHCI controllers, spl_mmc.c would actually choose
device sdhci0 even if booted from sdhci1 (boot_device). This is because
spl_mmc_get_device_index(boot_device) expects BOOT_DEVICE_MMC2[_2] in
order to return index 1 instead of 0.
The #if defined(...) statement is copied from board/xilinx/zynqmp/zynqmp.c
So the key to properly enabling both controllers as boot sources is
defining both CONFIG_ZYNQ_SDHCI0 and CONFIG_ZYNQ_SDHCI1 in your board's
include/configs/*.h.
