efi_loader: allow compiling with clang
On ARM systems gd is stored in register r9 or x18. When compiling with
clang gd is defined as a macro calling function gd_ptr(). So we can not
make assignments to gd.
In the UEFI sub-system we need to save gd when leaving to UEFI binaries and
have to restore gd when reentering U-Boot.
Define a new function set_gd() for setting gd and use it in the UEFI
sub-system.

efi_loader: validate load option
For passing the optional data of the load option to the loaded imaged

efi_deserialize_load_option() is changed to return the size of the optional

As a by-product we get a partial validation of the load option.
Checking the length of the device path remains to be implemented.
Some Coverity defects identified the load options as user input because
get_unaligned_le32() and get_unaligned_le16() is called. But non of these

Especially OP-TEE needs this to initialize dynamic shared memory

Parts of later SPL may need RAM information as well, so do full

initializes the ram information in gd.
dram_init() from sdram.c does the following steps:
- uclass_get_device(UCLASS_RAM, ...) like the current code
- ret = ram_get_info(dev, &ram);
- gd->ram_size = ram.size;
CONFIG_SPL_RAM already makes sure that sdram.c gets compiled
and thus no other variant of dram_init() can exist.
So it's the same functionality as before and only adds that the
SPL now aquires knowledge about the amount of available ram,
which it didn't know about before.

By default patman generates a combined changelog for the cover letter. This

Many patches may have the same changes. These can be coalesced with
"Series-process-log: uniq", but this is imperfect. Similar changes like
"Move foo to patch 7" will not be merged with the similar "Move foo to this
patch from patch 6".
Changes may not make sense outside of the patch they are written for. For
example, a change line of "Add check for bar" does not make sense outside
of the context in which bar might be checked for. Some changes like "New"
or "Lint" may be repeated many times throughout different change logs, but
carry no useful information in a summary.
Lastly, I like to summarize the broad strokes of the changes I have made in
the cover letter, while documenting all the details in the appropriate
patches. I think this makes it easier to get a good feel for what has
changed, without making it difficult to wade through every change in the
whole series.
This patch adds two new tags to add changelog entries which only appear in

When use this quirk, the controller implements a fixed 40-bit

misc: i2c_eeprom: implement different probe test eeprom offset
Because of this commit :
5ae84860b0 ("misc: i2c_eeprom: verify that the chip is functional at probe()")
at probe time, each eeprom is tested for read at offset 0.
The Atmel AT24MAC402 eeprom has different mapping. One i2c slave address is
used for the lower 0x80 bytes and another i2c slave address is used for the
upper 0x80 bytes. Because of this basically the i2c master sees 2 different
slaves. We need the upper bytes because we read the unique MAC address from
this EEPROM area.
However this implies that our slave address will return error on reads
from address 0x0 to 0x80.
To solve this, implemented an offset field inside platform data that is by
default 0 (as it is used now), but can be changed in the compatible table.
The probe function will now read at this offset and use it, instead of blindly
checking offset 0.
This will fix the regression noticed on these EEPROMs since the commit
abovementioned that introduces the probe failed issue.

i2c: designware_i2c: Check if the device is powered
If the device doesn't return a version that means the device is
non-functional.
The dw_i2c_regs had invalid offsets for the version field. I got the
correct value from the DesignWare databook. It also matches what the
Picasso PPR says.

i2c: designware_i2c: Tidy up use of NULL priv
At present we still have pre-driver-model code in this driver and it makes
things a bit confusing. In particular calc_bus_speed() is called with priv
as NULL if not using driver model.
This results in spk_cnt and comp_param1 being read from an invalid address
if not using driver model. For comp_param1 this may not cause problems if
reading from addresses close to 0 happens to be allowed, as high speed is
only supported by DM code. But spk_cnt is subsequently used to calculate
the bus periods and so this may cause problems (e.g. on spear600 board
which has not been migrated yet).
Add a new parameter regs parameter to calc_bus_speed() and add more
comments to this function and to _dw_i2c_set_bus_speed(), which calls it.

cbfs: Don't require the CBFS size with cbfs_init_mem()
The size is not actually used since it is present in the header. Drop this
parameter. Also tidy up error handling while we are here.

cbfs: Change file_cbfs_find_uncached() to return an error
This function currently returns a node pointer so there is no way to know
the error code. Also it uses data in BSS which seems unnecessary since the
caller might prefer to use a local variable.
Update the function and split its body out into a separate function so we
can use it later.
