video: exynos_fimd: Add framework to disable FIMD sysmmu
On Exynos5420 and newer versions, the FIMD sysmmus are in

We have to disable them in order to make FIMD DMA work.
This patch adds the required framework to exynos_fimd driver,

Previously, we used to statically assign values for vl_col, vl_row and
vl_bpix using #defines like LCD_XRES, LCD_YRES and LCD_COLOR16.
Introducing the function exynos_lcd_early_init() would take care of this
assignment on the fly by parsing FIMD DT properties, thereby allowing us
to remove LCD_XRES and LCD_YRES from the main config file.

arm:reset: call the reset_misc() before the cpu reset
On an Odroid U3 board, the SOC is unable to reset the eMMC card
in the DWMMC mode by the cpu software reset. Manual reset of the card
by switching proper gpio pin - fixes this issue.
Such solution needs to add a call to pre reset function.
This is done by the reset_misc() function, which is called before reset_cpu().
The function reset_misc() is a weak function.

ARM: Fix overflow in MMU setup
The patch fixes a corner case where adding size to DRAM start resulted
in a value (1 << 32), which in turn overflew the u32 computation, which
resulted in 0 and it therefore prevented correct setup of the MMU tables.
The addition of DRAM bank start and it's size can end up right at the end
of the address space in the special case of a machine with enough memory.
To prevent this overflow, shift the start and size separately and add them
only after they were shifted.
Hopefully, we only have systems in tree which have DRAM size aligned to
1MiB boundary. If not, this patch would break such systems. On the other
hand, such system would be broken by design anyway.

usb: hub: don't check CONNECTION in hub_port_reset()
One specific USB 3.0 device behaves strangely when reset by
usb_new_device()'s call to hub_port_reset(). For some reason, the device
appears to briefly drop off the bus when this second bus reset is
executed, yet if we retry this loop, it'll eventually come back after
another two resets.
If USB bus reset is executed over and over within usb_new_device()'s call
to hub_port_reset(), I see the following sequence of results, which
repeats as long as you want:
The device in question is a SanDisk Ultra USB 3.0 16GB memory stick with
USB VID/PID 0x0781/0x5581.
In order to allow this device to work with U-Boot, ignore the
{C_,}CONNECTION bits in the status/change registers, and only use the
ENABLE bit to determine if the reset was successful.
To be honest, extensive investigation has failed to determine why this
problem occurs. I'd love to know! I don't know if it's caused by:
* A HW bug in the device
* A HW bug in the Tegra USB controller
* A SW bug in the U-Boot Tegra USB driver
* A SW bug in the U-Boot USB core
This issue only occurs when the device's USB3 pins are attached to the
host; if only the USB2 pins are connected the issue does not occur. The
USB3 controller on Tegra is in reset, so is not actively communicating
with the device at all - a USB3 analyzer confirms this. Slightly
unplugging the device (so the USB3 pins don't contact) or using a USB2
cable or hub as an intermediary avoids the problem. For some reason,
the Linux kernel (either on the same Tegra board, or on an x86 host)
has no issue with the device, and I observe no disconnections during
reset.
This change won't affect any USB device that already works, since such
devices could not currently be triggering the error return this patch
removes, or they wouldn't be working currently.
However, this patch is quite reliable in practice, hence I hope it's
acceptable to solve the problem.
The only potential fallout I can see from this patch is:
* A broken device that triggers C_CONNECTION/!CONNECTION now causes the
loop in hub_port_reset() to run multiple times. If it never succeeds,
this will cause "usb start" to take roughly 1s extra to execute.
* If the user unplugs a device while hub_port_reset() is executing, and
very quickly swaps in a new device, hub_port_reset() might succeed on
the new device. This would mean that any information cached about the
original device (from the descriptor read in usb_new_device(), which
simply caches the max packet size) might be invalid, which would cause
problems talking to the new device. However, without this change, the
new device wouldn't work anyway, so this is probably not much of a
loss.

We noticed on the DXR2 platform (AM335x with a SMSC LAN9303 switch connected
to the CPSW MAC) that the network performance in U-Boot is quite poor. Only
when the transfer is started without a cable connected, and the cable is
plugged after the first timeout "T" occured, an increased in performance
can be seen. Debugging has revealed, that the cpsw driver has constant
link checking builtin into the rx and tx functions. This results in the
bad performance and seems to be unnecessary. The link has already been
checked in the init function, before the transfer is started. This usually
is sufficient.
BTW: I have seen no other network driver in U-Boot so far, that constantly
checks for link in the rx / tx functions.
The performance numbers on the DXR2 board are:
0.56 MiB/s cpsw_check_link() in rx and tx path
0.87 MiB/s cpsw_check_link() only in tx path
1.0 MiB/s cpsw_check_link() only in rx path
2.7 MiB/s no cpsw_check_link() in rx and tx path
