f320a4d845 bootm: Use selected configuration for ramdisk and fdt
If a specific configuraion is selected by the bootm command, e.g. with
'bootm 84000000#recoveryconf' we must honour this for not just the kernel,
but also the ramdisk and FDT.

In the conversion to using a common fit_image_load() function for loading
images from FITs (commits a51ec63 and 53f375f) this feature was lost.
Reinstate it by passing the selected configuration back from
fit_image_load() to boot_get_kernel(), then use this configuration
(which is stored in images->fit_uname_cfg) in both boot_get_ramdisk()
and boot_get_fdt().

970150a167 cmd_bootm.c: Re-order bootm_load_os return check for ELDK4.2
With ELDK4.2 we were getting a warning that load_end may be used
uninitialized in calling lmb_reserve.  This could not be the case,
however.  If we re-order the checks (and make them slightly clearer as
well) the warning goes away.  bootm_load_os may only return 0 on
success, BOOTM_ERR_OVERLAP in a non-fatal overlap (already covered in
comments) or a fatal BOOTM_ERR that is covered in the error handler.

fb1b139bb7 bootm: Add the missing PREP stage to bootz and correct image handling
In the recent bootm refactor, the PREP stage was missing in the bootz
command. This causes unpredictable behaviour.

The use of a local variable means that the reset of cmd_bootm.c does not
in fact use the same image structure, so remove this.

Also manually set the OS type to Linux, since this is the only possibility
at present, and we need to select the right boot function.

The original bootm code (before commit 35fc84f) did not check for a valid

With the move of the interrupt code to earlier in the sequence, we

d366438d8a cmd_bootm.c: Correct BOOTM_ERR_OVERLAP handling
With 35fc84fa1 [Refactor the bootm command to reduce code duplication]
we stopped checking the return value of bootm_load_os (unintentionally!)
and simply returned if we had a non-zero return value from the function.
This broke the valid case of a legacy image file of a single kernel
loaded into an overlapping memory area (the default way of booting
nearly all TI platforms).

The best way to fix this problem in the new code is to make
bootm_load_os be the one to see if we have a problem with this, and if
it's fatal return BOOTM_ERR_RESET and if it's not BOOTM_ERR_OVERLAP, so
that we can avoid calling lmb_reserve() but continue with booting.  We
however still need to handle the other BOOTM_ERR values so re-work
do_bootm_states so that we have an error handler at the bottom we can
goto for problems from bootm_load_os, or problems from the other callers
(as the code was before).  Add a comment to do_bootm_states noting the
existing restriction on negative return values.

ff8fef5666 Fix block device accesses beyond 2TiB
With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type,
which is required to represent block numbers for storage devices that
exceed 2TiB (the block size usually is 512B), e.g. recent hard drives.

For some obscure reason, the current U-Boot code uses lbaint_t for the
number of blocks to read (a rather optimistic estimation of how RAM
sizes will evolve), but not for the starting address. Trying to access
blocks beyond the 2TiB boundary will simply wrap around and read a
block within the 0..2TiB range.

We now use lbaint_t for block start addresses, too. This required
changes to all block drivers as the signature of block_read(),
block_write() and block_erase() in block_dev_desc_t changed.

against several types of attack. For example, it it possible to create a

to substitute a signed image from an older FIT version into a newer FIT
(roll-back attack).

19c402afa2 image: Add RSA support for image signing
RSA provides a public key encryption facility which is ideal for image
signing and verification.

Images are signed using a private key by mkimage. Then at run-time, the
images are verified using a private key.

This implementation uses openssl for the host part (mkimage). To avoid
bringing large libraries into the U-Boot binary, the RSA public key
is encoded using a simple numeric representation in the device tree.

d0ae31eb07 Add a 'fake' go command to the bootm command
For tracing it is useful to run as much of U-Boot as possible so as to get
a complete picture. Quite a bit of work happens in bootm, and we don't want
to have to stop tracing before bootm starts.

Add a way of doing a 'fake' boot of the OS - which does everything up to
the point where U-Boot is about to jump to the OS image. This allows
tracing to record right until the end.

35fc84fa1f Refactor the bootm command to reduce code duplication
At present the bootm code is mostly duplicated for the plain 'bootm'
command and its sub-command variant. This makes the code harder to
maintain and means that changes must be made to several places.

Introduce do_bootm_states() which performs selected portions of the bootm
work, so that both plain 'bootm' and 'bootm <sub_command>' can use the
same code.

Additional duplication exists in bootz, so tidy that up as well. This
is not intended to change behaviour, apart from minor fixes where the
previously-duplicated code missed some chunks of code.

983c72f479 Clarify bootm OS arguments
At present the arguments to bootm are processed in a somewhat confusing
way. Sub-functions must know how many arguments their calling functions
have processed, and the OS boot function must also have this information.
Also it isn't obvious that 'bootm' and 'bootm start' provide arguments in
the same way.

Adjust the code so that arguments are removed from the list before calling
a sub-function. This means that all functions can know that argv[0] is the
first argument of which they need to take notice.

adjust_size_for_badblocks reduces the operation size to account

Erase does not do block skipping, except for erase.spread which takes
a data amount rather than an interval (and thus already does not call
adjust_size_for_badblocks).  Calling adjust_size_for_badblocks when
block skipping is not done means that if bad blocks are present,
the "nand erase.part" and "nand erase.chip" commands will fail to erase
blocks at the end of the interval.

from the start.

This is useful when a single board may be stuffed with different eMMC

environment to be stored at the very end of the device (or eMMC boot
partition for example).

One example of this case is NVIDIA's Ventana reference board.

e82a316d7f usb: ehci: add Faraday USB 2.0 EHCI support
This patch adds support to both Faraday FUSBH200 and FOTG210,
the differences between Faraday EHCI and standard EHCI are
listed bellow:

1. The PORTSC starts at 0x30 instead of 0x44.
2. The CONFIGFLAG(0x40) is not only un-implemented, and
   also has its address space removed.
3. Faraday EHCI is a TDI design, but it doesn't
   compatible with the general TDI implementation
   found at both U-Boot and Linux.
4. The ISOC descriptors differ from standard EHCI in
   several ways. But since U-boot doesn't support ISOC,
   we don't have to worry about that.

064d55f8bc fdt: remove unaligned access in fdt_fixup_ethernet()
Some ARM compilers may emit code that makes unaligned accesses when
faced with constructs such as:

char mac[16] = "ethaddr";

Replace this with a strcpy() call instead to avoid this. strcpy() is
used here, rather than replacing all usage of the mac variable with the
string itself, since the loop itself sprintf()s to the variable each
iteration, so strcpy() is doing basically the same thing.

a0ba279ac6 generic_board: reduce the redundancy of gd_t struct members
This commit refactors common/board_f.c and common/board_r.c
in order to delete the dest_addr and dest_addr_sp from
gd_t struct.

As mentioned as follows in include/asm-generic/global_data.h,

  /* TODO: is this the same as relocaddr, or something else? */
  unsigned long dest_addr;        /* Post-relocation address of U-Boot */

dest_addr is the same as relocaddr.
Likewise, dest_addr_sp is the same as start_addr_sp.

It seemed dest_addr/dest_addr_sp was used only as a scratch variable
to calculate relocaddr/start_addr_sp, respectively.

With a little refactoring, we can delete dest_addr and dest_addr_sp.

6a195d2d8a lcd: add functions to set up simplefb device tree
simple-framebuffer is a new device tree binding that describes a pre-
configured frame-buffer memory region and its format. The Linux kernel
contains a driver that supports this binding. Implement functions to
create a DT node (or fill in an existing node) with parameters that
describe the framebuffer format that U-Boot is using.

This will be immediately used by the Raspberry Pi board in U-Boot, and
likely will be used by the Samsung ARM ChromeBook support soon too. It
could well be used by many other boards (e.g. Tegra boards with built-in
LCD panels, which aren't yet supported by the Linux kernel).

99bd544ee7 fdt: allow bootdelay to be specified via device tree
This can be useful to force bootcmd to execute as soon as U-Boot has
started.

My use-case is: An SoC-specific tool pushes U-Boot into RAM, along with
an image to be written to device boot flash, with the DT config property
"bootcmd" set to contain a command to write that image to flash. In this
scenario, we don't want to allow any stale bootdelay value taken from
the current flash content to affect how long it takes before the
flashing process starts.

dfe64e2c89 mtd: resync with Linux-3.7.1
This patch is essentially an update of u-boot MTD subsystem to
the state of Linux-3.7.1 with exclusion of some bits:

- the update is concentrated on NAND, no onenand or CFI/NOR/SPI
flashes interfaces are updated EXCEPT for API changes.

- new large NAND chips support is there, though some updates
have got in Linux-3.8.-rc1, (which will follow on top of this patch).

To produce this update I used tag v3.7.1 of linux-stable repository.

The update was made using application of relevant patches,
with changes relevant to U-Boot-only stuff sticked together
to keep bisectability. Then all changes were grouped together
to this patch.
