This patch adds support for parallel NOR device (S29GL512S10) present on J6-EVM.
The Flash device is connected to GPMC controller on chip-select[0] and accessed
as memory-mapped device. It has data-witdh=x16, capacity-64MBytes(512Mbits) and
is CFI compatible.
As multiple devices are share GPMC pins on this board, so following board
settings are required to detect NOR device:
SW5.1 (NAND_BOOTn) = OFF (logic-1)
SW5.2 (NOR_BOOTn) = ON (logic-0) /* Active-low */
SW5.3 (eMMC_BOOTn) = OFF (logic-1)
SW5.4 (QSPI_BOOTn) = OFF (logic-1)
And also set appropriate SYSBOOT configurations:
SW3.1 (SYSBOOT[ 8])= ON (logic-1) /* selects SYS_CLK1 speed */
SW3.2 (SYSBOOT[ 9])= OFF (logic-0) /* selects SYS_CLK1 speed */
SW3.3 (SYSBOOT[10])= ON (logic-1) /* wait-pin monitoring = enabled */
SW3.4 (SYSBOOT[11])= OFF (logic-0) /* device type: Non Muxed */
SW3.5 (SYSBOOT[12])= OFF (logic-0) /* device type: Non Muxed */
SW3.6 (SYSBOOT[13])= ON (logic-1) /* device bus-width: 1(x16) */
SW3.7 (SYSBOOT[14])= OFF (logic-0) /* reserved */
SW3.8 (SYSBOOT[15])= ON (logic-1) /* reserved */
Also, following changes are required to enable NOR Flash support in
dra7xx_evm board profile:
This patch adds support for NAND device connected to GPMC chip-select on
following AM43xx EVM boards.
am437x-gp-evm: On this board, NAND Flash signals are muxed with eMMC, thus at a
time either eMMC or NAND can be enabled. Selection between eMMC and NAND is
controlled by:
(a) Statically using Jumper on connecter (J89) present on board.
(a) If Jumper on J89 is NOT used, then selection can be dynamically controlled
by driving SPI2_CS0[MUX_MODE=GPIO] pin via software:
SPI2_CS0 == 0: NAND (default)
SPI2_CS0 == 1: eMMC
am43x-epos-evm: On this board, NAND Flash control lines are muxed with QSPI,
Thus only one of the two can be used at a time. Selection is controlled by:
(a) Dynamically driving following GPIO pin from software
GPMC_A0(GPIO) == 0 NAND is selected (default)
NAND device (MT29F4G08AB) on these boards has:
- data-width=8bits
- blocksize=256KB
- pagesize=4KB
- oobsize=224 bytes
For above NAND device, ROM code expects the boot-loader to be flashed in BCH16
ECC scheme for NAND boot, So by default BCH16 ECC is enabled for AM43xx EVMs.

This patch adds support of NOR cape[1] for both Beaglebone (white) and
Beaglebone(Black) boards. NOR Flash on this cape is connected to GPMC
chip-select[0] and accesses as external memory-mapped device.
This cape has 128Mbits(16MBytes), x16, CFI compatible NOR Flash device.
As GPMC chip-select[0] can be shared by multiple capes so NOR profile is
not enabled by default in boards.cfg. Following changes are required to
enable NOR cape detection when building am335x_boneblack board profile.

Beaglebone Board can be connected to expansion boards to add devices to them.
These expansion boards are called 'capes'. This patch adds support for
following versions of Beaglebone(AM335x) NAND capes
(a) NAND Device with bus-width=16, block-size=128k, page-size=2k, oob-size=64
(b) NAND Device with bus-width=16, block-size=256k, page-size=4k, oob-size=224
Further information and datasheets can be found at [1] and [2]
* How to boot from NAND using Memory Expander + NAND Cape ? *
- Important: As BOOTSEL values are sampled only at POR, so after changing any
setting on SW2 (DIP switch), disconnect and reconnect all board power supply
(including mini-USB console port) to POR the beaglebone.
- Selection of ECC scheme
for NAND cape(a), ROM code expects BCH8_HW ecc-scheme
for NAND cape(b), ROM code expects BCH16_HW ecc-scheme
- Selction of boot modes can be controlled via DIP switch(SW2) present on
Memory Expander cape.
SW2[SWITCH_BOOT] == OFF follow default boot order MMC-> SPI -> UART -> USB
SW2[SWITCH_BOOT] == ON boot mode selected via DIP switch(SW2)
So to flash NAND, first boot via MMC or other sources and then switch to
SW2[SWITCH_BOOT]=ON to boot from NAND Cape.
- For NAND boot following switch settings need to be followed
SW2[ 1] = OFF (SYSBOOT[ 0]==1: NAND boot mode selected )
SW2[ 2] = OFF (SYSBOOT[ 1]==1: -- do -- )
SW2[ 3] = ON (SYSBOOT[ 2]==0: -- do -- )
SW2[ 4] = ON (SYSBOOT[ 3]==0: -- do -- )
SW2[ 5] = OFF (SYSBOOT[ 4]==1: -- do -- )
SW2[ 6] = OFF (SYSBOOT[ 8]==1: 0:x8 device, 1:x16 device )
SW2[ 7] = ON (SYSBOOT[ 9]==0: ECC done by ROM )
SW2[ 8] = ON (SYSBOOT[10]==0: Non Muxed device )
SW2[ 9] = ON (SYSBOOT[11]==0: -- do -- )

*IMPORTANT NOTE*
As Beaglebone board shares the same config as AM335x EVM, so following
changes are required in addition to this patch for Beaglebone NAND cape.
(1) Enable NAND in am335x_beaglebone board profile
(2) Add CONFIG_SYS_NAND_BUSWIDTH_16BIT to board config because:
- AM335x EVM has NAND device with datawidth=8, whereas
- Beaglebone NAND cape has NAND device with data-width=16
This patch
- consolidate CONFIG_SYS_NAND_xx and CONFIG_SPL_NAND_xx from various
configuration files into single file.
- update MTD Partition table to match AM335x_EVM DT in linux-kernel
- segregate CONFIGs based on different boot modes (like SPL and U-Boot)

When compiling the current code on GCC 4.8.3, the following warnings
appear:
warning: format '%zu' expects argument of type 'size_t', but argument
2 has type 'long unsigned int' [-Wformat=]
There were many mails about such warnings on different architectures.
This patch limits itself to the nios2 architecture.
The problem is that for the size_t (%zu, %zd, ...) arguments of
printf GCC does not verify the type match to size_t type. It verifies
the type match to the compiler-defined __SIZE_TYPE__ type. Thus, if
size_t is defined different from __SIZE_TYPE__ - warnings inevitably
appear.
There is a comment by Thomas Chou to the (rejected) patch:
http://patchwork.ozlabs.org/patch/272102/
which explains that the older GCC toolchains (gcc-3.4.6 and gcc-4.1.2)
expect size_t to be "unsigned long" and the newer expect it to be
"unsigned int". Thus, no matter how we define size_t - either way
warnings appear when using some GCC version.
By rejecting that patch, a choice was made to prefer older GCC versions
and leave the warnings when building with the newer toolchains.
Personally, I disagree with this choice...
In any case, this patch proposes a way to fix the warnings for any GCC
version. Just define size_t using the __SIZE_TYPE__ compiler-defined
type and the type verification will pass.
I tested that this fixes the warning on GCC 4.8.3. I don't have an
older toolchain to test with, but __SIZE_TYPE__ was definitely defined
in GCC 3.4.6, so it should work there too.

Commit 51148790 added scripts/multiconfig.py written in Python 2
to adjust Kconfig for U-Boot.
It has been hard for Python 3 users because Python 2 and Python 3
are not compatible with each other.
We are not happy about adding a new host tool dependency
(in this case, Python version dependency) for the core build process.
After some discussion, we decided to use only basic tools.
The script may get a bit more unreadable by shell scripting,
but we believe it is worthwhile.
In addition, this commit revives "<board>_config" target that is
equivalent to "<board>_defconfig" for backwards compatibility.
It is annoying to adjust various projects which use U-Boot.

It's not unusual for DHCP servers to take a couple hundred milliseconds
to respond to DHCP discover messages. One possible reason for the delay
can be that the server checks (typically using an ARP request) that the
IP it's about to hand out isn't in use yet. To make matters worse, some
servers may also queue up requests and process them sequentially, which
can cause excessively long delays if clients retry too fast.
Commit f59be6e850 ("net: BOOTP retry timeout improvements") shortened
the retry timeouts significantly, but the BOOTP/DHCP implementation in
U-Boot doesn't handle that well because it will ignore incoming replies
to earlier requests. In one particular setup this increases the time it
takes to obtain a DHCP lease from 630 ms to 8313 ms.
This commit attempts to fix this in two ways. First it increases the
initial retry timeout from 10 ms to 250 ms to give DHCP servers some
more time to respond. At the same time a cache of outstanding DHCP
request IDs is kept so that the implementation will know to continue
transactions even after a retransmission of the DISCOVER message. The
maximum retry timeout is also increased from 1 second to 2 seconds. An
ID cache of size 4 will keep DHCP requests around for 8 seconds (once
the maximum retry timeout has been reached) before dropping them. This
should give servers plenty of time to respond. If it ever turns out
that this isn't enough, the size of the cache can easily be increased.
With this commit the DHCP lease on the above-mentioned setup still takes
longer (1230 ms) than originally, but that's an acceptable compromise to
improve DHCP lease acquisition time for a broader range of setups.
To make it easier to benchmark DHCP in the future, this commit also adds
the time it took to obtain a lease to the final "DHCP client bound to
address x.x.x.x" message.

In Python, sys.exit() function can also take an object other
than an integer.
If an integer is given to the argument, Python exits with the return
code of it. If a non-integer argument is given, Python outputs it
to stderr and exits with the return code of 1.
That means,
print >> sys.stderr, "Blah Blah"
sys.exit(1)
is equivalent to
sys.exit("Blah Blah")
The latter is a useful shorthand.
