Patch queue for efi - 2018-09-26
A lot of goodness in this release. We're *very* close to running the
UEFI Shell and SCT natively. The only missing piece are HII protocols.
- FAT write support (needed for SCT)
- improved FAT directory support (needed for SCT)
- RTC support with QEMU -M virt
- Sandbox support (run UEFI binaries in Linux - yay)
- Proper UTF-16 support
- EFI_UNICODE_COLLATION_PROTOCOL support (for UEFI Shell)
- EFI_SIMPLE_TEXT_INPUT_EX_PROTOCOL support (for UEFI Shell)
- Fix window size determination
- Fix Tegra by explicitly unmapping RAM
- Clean up handle entanglement
- Lots of generic code cleanup

Now that we have the pinctrl driver for Merrifield in place we can make
use of it and set I2C#6 pins appropriately.
Initial configuration came from the firmware. Which quite likely has
been used in the phones, where that is not part of Atom peripheral, is
in use. Thus we need to override the leftover.

This API is going to be used to configure some pins that are protected
for simple modification.
It's not a comprehensive pinctrl driver but can be turned into one
when we need this in the future. Now it is planned to be used only
in one place. So that's why I decided not to pollute the codebase with a
full-blown pinctrl-merrifield nobody will use.
This driver reads corresponding fields in DT and configures pins
accordingly.
The "protected" flag is used to distinguish configuration of SCU-owned
pins from the ordinary ones.
The code has been adapted from Linux work done by Andy Shevchenko
in pinctrl-merrfifield.c

In int-ll64.h, we always use the following typedefs:
typedef unsigned int u32;
typedef unsigned long uintptr_t;
typedef unsigned long long u64;
This does not need to match to the compiler's <inttypes.h>.
Do not include it.
The use of PRI* makes the code super-ugly. You can simply use
"l" for printing uintptr_t, "ll" for u64, and no modifier for u32.

All architectures have the same definition for s8/16/32/64

BTW, Linux unified the kernel space definition into int-ll64.h

You do not need to use the typedefs provided by compiler.
Our compilers are either IPL32 or LP64. Hence, U-Boot can/should
always use int-ll64.h typedefs like Linux kernel, whatever the
typedefs the compiler internally uses.

As of today, the proposal of adding "acpi_rsdp_addr" to the kernel
boot protocol does not make its way to the kernel mainline. This
creates some confusion if we leave it in the U-Boot code base.
Remove it for now until we have a clear picture with kernel upstream.
Note this eventually does a partial revert to commit 3469bf427454

At present Linux kernel loaded from U-Boot as an EFI payload does
not boot. This fills in kernel's boot params structure with the
required critical EFI information like system table address and
memory map stuff so that kernel can obtain essential data like
runtime services and ACPI table to boot.
With this patch, now U-Boot as an EFI payload becomes much more
practical: it is another option of kernel bootloader, ie, can be
a replacement for grub.

Patch queue for efi - 2018-08-21
A few fixes for 2018.09. Most noticable are:
- unbreak x86 target (-fdata-section fallout)
- fix undefined behavior in a few corner cases
- make Jetson TX1 boot again
- RTS fixes
- implement reset for simple output
|
|
We left -fdata-sections disabled for x86_64 before because we encountered
random bugs that were at that time inexplicable.
Turns out this really was just side effects of missing .bss* statements
in the linker scripts. With those fixed, we can enable data sections for all
targets.

When we build with -fdata-sections we may end up with bss subsections. Our

Currently building U-Boot as the coreboot payload requires user
to change the build configuration for a specific board during
menuconfig process. This uses the board's native device tree
to configure the hardware. For example, the device tree provides
PCI address range for the PCI host controller and U-Boot will
re-program all PCI devices' BAR to be within this range. In order
to make sure we don't mess up the hardware, we should guarantee
the range matches what coreboot programs the chipset.
But we really should make the coreboot payload support easier.
Just like EFI payload, we can create a generic coreboot payload
for all x86 boards as well. The payload is configured to include
as many generic drivers as possible. All stuff that touches low
level initialization are not allowed as such is the coreboot's
responsibility. Platform specific drivers (like gpio, spi, etc)
are not included.

After some thought, I believe there is an unfortunate naming flaw in
binman. Entries have a position and size, but now that we support
hierarchical sections it is unclear whether a position should be an
absolute position within the image, or a relative position within its
parent section.
At present 'position' actually means the relative position. This indicates
a need for an 'image position' for code that wants to find the location of
an entry without having to do calculations back through parents to
discover this image position.
A better name for the current 'position' or 'pos' is 'offset'. It is not
always an absolute position, but it is always an offset from its parent
offset.
It is unfortunate to rename this concept now, 18 months after binman was
introduced. However I believe it is the right thing to do. The impact is
mostly limited to binman itself and a few changes to in-tree users to
binman:
tegra
sunxi
x86
The change makes old binman definitions (e.g. downstream or out-of-tree)
incompatible if they use the 'pos = <...>' property. Later work will
adjust binman to generate an error when it is used.

Some times gcc may generate data that is then used within code that may
be part of an efi runtime section. That data could be jump tables,
constants or strings.
In order to make sure we catch these, we need to ensure that gcc emits
them into a section that we can relocate together with all the other
efi runtime bits. This only works if the -ffunction-sections and
-fdata-sections flags are passed and the efi runtime functions are
in a section that starts with ".text".
Up to now we had all efi runtime bits in sections that did not
interfere with the normal section naming scheme, but this forces
us to do so. Hence we need to move the efi_loader text/data/rodata
sections before the global *(.text*) catch-all section.
With this patch in place, we should hopefully have an easier time
to extend the efi runtime functionality in the future.

Since commit bb0bb91cf0aa ("efi_stub: Use efi_uintn_t"), EFI x86
64-bit payload does not work anymore. The call to GetMemoryMap()
in efi_stub.c fails with return code EFI_INVALID_PARAMETER. Since
the payload itself is still 32-bit U-Boot, efi_uintn_t gets wrongly
interpreted as int, but it should actually be long in a 64-bit EFI
environment.
This changes the x86 __kernel_size_t conditionals to use compiler
provided defines instead. That way we always adhere to the build
environment we're in and the definitions adjust automatically.
