There are ARM systems which are essentially heterogeneous multicores where
some cores implement a different ARM architecture version than other cores. A
specific example is the tegra124 which boots on an ARMv4 coprocessor while
most code, including most of the firmware, runs on the main ARMv7 core. To
support SOCs like this, the plan is to generalize the ARM architecture so that
all versions are available, and an SOC/CPU can then select what architecture
variant should be used for each component of the firmware; bootblock,
romstage, and ramstage.

ARM: Split out ARMv7 code and make it possible to have other arch versions.
We don't always want to use ARMv7 code when building for ARM, so we should
separate out the ARMv7 code so it can be excluded, and also make it possible
to include code for some other version of the architecture instead, all per
build component for cases where we need more than one architecture version
at a time.
The tegra124 bootblock will ultimately need to be ARMv4, but until we have
some ARMv4 code to switch over to we can leave it set to ARMv7.

Now some Linuxes (depending on their glibc) also fail on it, so just
remove the call altogether at the cost of some leaked memory (couple
hundred kilobytes) because tracking down the precise fix is too hard.
In case someone wants to fix it, valgrind sees the issues, so

The Linux trampoline code does not set up the segment descriptors for
__BOOT_CS and __BOOT_DS as described in the Linux kernel
documentation:
... a GDT must be loaded with the descriptors for selectors
__BOOT_CS(0x10) and __BOOT_DS(0x18); both descriptors must be 4G
flat segment; __BOOT_CS must have execute/read permission, and
__BOOT_DS must have read/write permission;
This is not a problem when launching a Linux payload from coreboot, as
coreboot configures the segment descriptors at selectors 0x10 and
0x18. Coreboot configures these selectors in the ramstage to match
what the Linux kernel expects (see
coreboot/src/arch/x86/lib/c_start.S).
When the cbfs payload is launched in other environments, SeaBIOS for
example, the segment descriptors are configured differently and the
cbfs Linux payload does not work.
If the cbfs Linux payload is to be used in multiple environments
should the trampoline needs to take care of the descriptors that Linux
requires.
This patch updates the Linux trampoline code to configure the 4G flat
descriptors that Linux expects. The configuration is borrowed from
the descriptor configs in coreboot/src/arch/x86/lib/c_start.S for
selectors 0x10 and 0x18.
The linux_trampoline code is slightly refractored by defining the
trampoline entry address, 0x40000, as TRAMPOLINE_ENTRY_LOC. This
definition is moved into a separate header file, linux_trampoline.h.
This header file is now included by both the trampoline assembly
language code and the trampoline loader C code.
The trampoline assembly language code can now use TRAMPOLINE_ENTRY_LOC
as scratch space for the sgdt CPU instruction.
Testing Done:
Verified the Linux payload is booted correctly in the following
environments:
1. Coreboot -> Linux Payload
2. Coreboot -> SeaBIOS -> Linux Payload: (previously did not work)

This patch represents a major overhaul of the USB enumeration code in
order to make it cleaner and much more robust to weird or malicious
devices. The main improvement is that it correctly parses the USB
descriptors even if there are unknown descriptors interspersed within,
which is perfectly legal and in particular present on all SuperSpeed
devices (due to the SuperSpeed Endpoint Companion Descriptor).
In addition, it gets rid of the really whacky and special cased
get_descriptor() function, which would read every descriptor twice
whether it made sense or not. The new code makes the callers allocate
descriptor memory and only read stuff twice when it's really necessary
(i.e. the device and configuration descriptors).
Finally, it also moves some more responsibilities into the
controller-specific set_address() function in order to make sure things
are initialized at the same stage for all controllers. In the new model
it initializes the device entry (which zeroes the endpoint array), sets
up endpoint 0 (including MPS), sets the device address and finally
returns the whole usbdev_t structure with that address correctly set.
Note that this should make SuperSpeed devices work, but SuperSpeed hubs
are a wholly different story and would require a custom hub driver
(since the hub descriptor and port status formats are different for USB
3.0 ports, and the whole issue about the same hub showing up as two
different devices on two different ports might present additional
challenges). The stack currently just issues a warning and refuses to
initialize this part of the hub, which means that 3.0 devices connected
through a 3.0 hub may not work correctly.

core and moves some definitions around in preparation of later changes

SetAddress() recovery delay and removes pointless additional delays from

This patch fixes a bug in the XHCI stack that occurs when a multi-TRB TD
times out before the last TRB is processed. The driver will correctly
issue a Stop Endpoint command in that case, but the xHC will still
preserve the transfer state and just pick up right after that on the
next doorbell ring. It will then process the leftover TRBs from the old
TD the next time a transfer is issued. (cf. XHCI 4.6.9)
We fix this by changing the existing xhci_reset_endpoint() calls in
transfer functions to not only trigger on Halted (2) and Error (4), but
also on Stopped (3). That function will not actually issue a Reset
Endpoint command in this case, but it will nuke the whole transfer ring
and issue a Set TR Dequeue Pointer command, which is sufficient (though
slightly overkill) to solve our problem.

The AGESA dispatcher is built using its own rules rather than
generic library generation rules in coreboot/Makefile and

copied from whereever they live into coreboot/build/agesa.
They are compiled from there. The binary PI directory has a
mandatory structure that places the AGESA BLOB into the same
directory as the support headers. These will nominally be
placed in the 3rdparty directory in coreboot.org.
The copy commands that were added to the the vendorcode
Makefile.inc ensure that only one thread will operate on each
source file by using a macro to generate the copy targets.
After the change, each copy target will operate on exactly one
source file.
Due to API issues, coreboot has no way to control the IMC to set up
fan control. Set a Kconfig flag that removes the ability to install
an IMC BLOB into CBFS.

tegra124: Add a test function which spams exclamation points on the UART.
This function spews characters on the console and, until we have a working
console, is an easy way to see whether the system boots to a particular point.
For some reason waiting for transmitter to be empty hangs, but transmitting
characters still works.

tegra124: Re-enable waiting for the transmitter to empty in the test function.
The compiler was emitting code compatible with armv7-a, but the bootblock was
running on a core which uses armv4t. By coincidence, it was emitting an
instruction which is unavailable on armv4t when checking the value of the
UART's LSR register. Now that the bootblock is compiled with more appropriate
flags, this code can be re-introduced.

tegra124: Seperate out the non-UART specific hardcoded init in the bootblock.
The hardcoded init in the test function in the bootblock is actually useful
generally because it doesn't belong in the UART driver itself but is necessary
for the UART to work. Until we have real implementations for the pinmux, etc.,
we can use that code to get the UART and console going.

tegra124: Implement and enable serial console support for tegra124.
The driver is very similar to the 8250 driver, except it isn't in two parts,
and it also spaces its registers 4 bytes apart instead of having them directly
adjacent to each other.
Also, eliminate the UART test function in the bootblock. It's no longer needed
since the actual console output serves the same purpose.
Right now the clock divisor is fixed for now, and we'll want to actually
figure out what value to use at some point.

Squashed 4 commits related to uart support for tegra124. Modified the
new uart.c to look like the uart.c for exynos5420.

The exynos directories had been moved from src/cpu to src/soc, but the name
of the chip_operations structure wasn't updated properly. That meant that the
SOCs never installed their memory resources and the ram stage would fail to
load the payload.

This minor refactoring patch changes the signature of all limited cache
invalidation functions in coreboot and libpayload from unsigned long to
void * for the address argument, since that's really what you have in
95% of the cases and I think it's ugly to have casting boilerplate all
over the place.
