At present stdio device functions do not get any clue as to which stdio
device is being acted on. Some implementations go to great lengths to work
around this, such as defining a whole separate set of functions for each
possible device.
For driver model we need to associate a stdio_dev with a device. It doesn't
seem possible to continue with this work-around approach.
Instead, add a stdio_dev pointer to each of the stdio member functions.
Note: The serial drivers have the same problem, but it is not strictly
necessary to fix that to get driver model running. Also, if we convert
serial over to driver model the problem will go away.
Code size increases by 244 bytes for Thumb2 and 428 for PowerPC.

If we are to have driver model before relocation we need to support some
way of calling memory allocation routines.
The standard malloc() is pretty complicated:
1. It uses some BSS memory for its state, and BSS is not available before
relocation
2. It supports algorithms for reducing memory fragmentation and improving
performace of free(). Before relocation we could happily just not support
free().
3. It includes about 4KB of code (Thumb 2) and 1KB of data. However since
this has been loaded anyway this is not really a problem.
The simplest way to support pre-relocation malloc() is to reserve an area
of memory and allocate it in increasing blocks as needed. This
implementation does this.
To enable it, you need to define the size of the malloc() pool as described
in the README. It will be located above the pre-relocation stack on
supported architectures.
Note that this implementation is only useful on machines which have some
memory available before dram_init() is called - this includes those that
do no DRAM init (like tegra) and those that do it in SPL (quite a few
boards). Enabling driver model preior to relocation for the rest of the
boards is left for a later exercise.

When this option is enabled, CRLF is treated like LF when importing environments

Drawback of enabling this option is that (maybe exported) variables which have

drawback is very unlikely and the big advantage of letting Windows user create

Similar to the USB NIC found on OMAP5uEVM, PandaBoard and BeagleBoard-XM
boards, the sunxi SoCs have a NIC onboard without an embedded MAC address.
Just like the omap used on these boards, the sunxi SoCs do have a unique chip
id, in the form of the 128 bit SID register:
http://linux-sunxi.org/SID_Register_Guide
So mimick the BeagleBoard-XM board code (commit 548a64d8) and use the chip id
to generate a unique fixed MAC address.
We check for the SID not being all 0, since some early A20 batches
shipped without having there SID programmed.
Note we use specific parts of the 128 bits, since some parts indicate the
SoC family / revision, and thus are fixed. The algorithm for this was taken
from the linux-sunxi.org kernels.

Also we remove the FAT_ENV_DEVICE and FAT_ENV_PART. We use a string:
FAT_ENV_DEVICE_AND_PART.

The DMA code in sunxi_mmc.c is broken. mmc_trans_data_by_dma() allocates the
dma descriptors on the stack, and then exits while the dma transfer is in
progress, so the dma engine is reading stack memory which at that point may
be re-used. So far we've gotten away with this by luck, but recent u-boot
changes have shifted the stack start address by 16 bytes, which combined
with dma alignment now exposes this problem.

use semihosting to load the kernel/ramdisk/dtb. This eliminates the need
for a bootwrapper and produces a more realistic boot sequence with
virtual models.
Though the semihosting code is quite generic, support for armv7 in
fastmodel is less useful due to the wide range of available silicon
and the lack of a free armv7 fastmodel, so this change contains an

In a very few cases we need to adjust the driver model root device, such as

Signed-off-by: Simon Glass <sjg@chromium.org>
When debugging drivers it is useful to see what I/O accesses were done
and in what order.
Even if the individual accesses are of little interest it can be useful to
verify that the access pattern is consistent each time an operation is
performed. In this case a checksum can be used to characterise the operation
of a driver. The checksum can be compared across different runs of the
operation to verify that the driver is working properly.
In particular, when performing major refactoring of the driver, where the
access pattern should not change, the checksum provides assurance that the
refactoring work has not broken the driver.
Add an I/O tracing feature and associated commands to provide this facility.
It works by sneaking into the io.h heder for an architecture and redirecting
I/O accesses through its tracing mechanism.
For now no commands are provided to examine the trace buffer. The format is
fairly simple, so 'md' is a reasonable substitute.
Note: The checksum feature is only useful for I/O regions where the contents
do not change outside of software control. Where this is not suitable you can
fall back to manually comparing the addresses. It might be useful to enhance
tracing to only checksum the accesses and not the data read/written.

this, we need to restrict this relocation process to use lower parts of
RAM that area accessible.
For the DTB, an earlier patch of mine set CONFIG_SYS_BOOTMAPSZ. However,
since some platforms have different restrictions on DTB and initrd
location, that config option doesn't affect the initrd. We need to set
the initrd_high environment variable to control the initrd relocation.
Since we have carefully chosen the load addresses for the DTB and
initrd (see comments in include/configs/tegraNNN-common.h re: values in
MEM_LAYOUT_ENV_SETTINGS), we don't actually need any DTB or initrd
relocation at all. Skipping relocation removes some redundant work.
Hence, set both fdt_high and initrd_high to ffffffff which completely
disables relocation.
If the user does something unusual, such as using custom locations for
the DTB/initrd load address or wanting to use DTB/initrd relocation for
some reason, they can simply set these variables to custom values to
override these environment defaults.
With this change, cmd_sysboot works correctly for a filesystem created
by the Fedora installer.

Commit e9fd66defd (ARM: mx6: define CONFIG_ARM_ERRATA_742230) enables
errata 742230 for imx6, because it helps remove one reboot issue.
However, this errata does not really apply on imx6, because Cortex-A9
on imx6 is r2p10 while the errata only applies to revisions r1p0..r2p2.
At a later time, commit f71cbfe3ca (ARM: Add workaround for Cortex-A9
errata 794072) adds support of errata 794072, which applies to all
Cortex-A9 revisions. As the workaround for both errata are exactly
same, it makes a lot more sense to select 794072 instead of 742230 for
imx6. Since we already enable 794072 for imx6, it's time to drop
errata 742230 to avoid confusion.

directly by ROM (memory mapped NOR or QSPI) we need to make use of the

This patch add support for BCH16_ECC to omap_gpmc driver.
*need to BCH16 ECC scheme*
With newer SLC Flash technologies and MLC NAND, and large densities, pagesizes
Flash devices have become more suspectible to bit-flips. Thus stronger
ECC schemes are required for protecting the data.
But stronger ECC schemes have come with larger-sized ECC syndromes which require
more space in OOB/Spare. This puts constrains like;
(a) BCH16_ECC can correct 16 bit-flips per 512Bytes of data.
(b) BCH16_ECC generates 26-bytes of ECC syndrome / 512B.
Due to (b) this scheme can only be used with NAND devices which have enough
OOB to satisfy following equation:
OOBsize per page >= 26 * (page-size / 512)

GPMC controller needs to be configured based on bus-width of the NAND device
connected to it. Also, dynamic detection of NAND bus-width from on-chip ONFI
parameters is not possible in following situations:
SPL: SPL NAND drivers does not support ONFI parameter reading.
U-boot: GPMC controller iniitalization is done in omap_gpmc.c:board_nand_init()
which is called before probing for devices, hence any ONFI parameter
information is not available during GPMC initialization.
Thus, OMAP NAND driver expected board developers to explicitely write GPMC
configurations specific to NAND device attached on board in board files itself.
But this was troublesome for board manufacturers as they need to dive into
lengthy platform & SoC documents to find details of GPMC registers and
appropriate configurations to get NAND device working.
This patch instead adds existing CONFIG_SYS_NAND_BUSWIDTH_16BIT to board config
hich indicates that connected NAND device has x16 bus-width. And then based on
this config GPMC driver itself initializes itself based on NAND bus-width. This
keeps board developers free from knowing GPMC controller specific internals.

As per following Sections in ONFI Spec, GET_FEATURES and SET_FEATURES also need
byte-addressing on 16-bit devices.
*Section: Target Initialization"
"The Read ID and Read Parameter Page commands only use the lower 8-bits of the
data bus. The host shall not issue commands that use a word data width on x16
devices until the host determines the device supports a 16-bit data bus width
in the parameter page."
*Section: Bus Width Requirements*
"When the host supports a 16-bit bus width, only data is transferred at the
16-bit width. All address and command line transfers shall use only the lower
8-bits of the data bus. During command transfers, the host may place any value
on the upper 8-bits of the data bus. During address transfers, the host shall
set the upper 8-bits of the data bus to 00h."
So porting following commit from linux kernel

"The Read ID and Read Parameter Page commands only use the lower 8-bits of the

mtd: nand: force NAND_CMD_READID onto 8-bit bus
Author: Brian Norris <computersforpeace@gmail.com> (preserving authorship)
The NAND command helpers tend to automatically shift the column address
for x16 bus devices, since most commands expect a word address, not a
byte address. The Read ID command, however, expects an 8-bit address
(i.e., 0x00, 0x20, or 0x40 should not be translated to 0x00, 0x10, or
0x20).
This fixes the column address for a few drivers which imitate the
nand_base defaults.
