When CONFIG_DM_DEVICE_REMOVE is not enabled, such as in SPL, we cannot
remove or unbind devices and do not expect to get errors when binding
and probing devices. So drop the error path to reduce code size.

The printf() in panic() adds about 1.5KB of code size to SPL when compiled

The CONFIG_DM_DEVICE_REMOVE option takes out code related to removing
devices. It should also remove the 'unbind' code since if we cannot
remove we probably don't need to unbind.

Since a device can have children in the same uclass as itself, we need
to handle unbinding carefully: we must allow that unbinding a device in a
uclass may cause another device in the same uclass to be unbound.

This commit extends the driver model uclass's API by function:
- uclass_get_device_by_name()
And this function returns the device if:
- uclass with given ID, exists,
- device with exactly given name(dev->name), exists,
- device probe, doesn't return an error.
The returned device is activated and ready to use.
Note:
This function returns the first device, which name is equal
to the given one. This means, that using this function you must
assume, that the device name is unique in the given uclass's ID
device list.

commit aed2fbef5e
"dm: serial: Tidy up the pl01x driver"
caused a regression on (real hardware) PL010 by omitting
to update the line control register when switching baudrate.
Fix this by inlining the missing write to the baud control
register.
Also renaming the set_line_control() function to
pl011_set_line_control() since this function is clearly
PL011-specific, and it won't suffice to call that to
set up line control.
Tested on the Integrator/AP hardware.

Some Realtek Ethernet PHYs, like RTL8211D(G/N) and RTL8211E(G), have
interrupts enabled by default. If the interrupt is not treated later by
the OS and the PHY's interrupt line is enabled and shared with other
interrupts, the system will get an interrupt storm. This patch disables
the interrupt for PHY devices that use one of the current Realtek
Ethernet PHY drivers. Some of Realtek Ethernet PHYs, such as RTL8211B(L)
have the interrupt masked. In this case, the functionality of the PHY
should not be afected since this patch brings INER and INSR registers to
their default values.

According to the MPC8555/MPC8541 reference manual the SS_EN (source
synchronous enable) bit in the DDR_SDRAM_CLK_CNLT register must be set
during initialization.
>From section 9.4.1.8 of that manual:
Source synchronous enable. This bit field must be set during
initialization. See Section 9.6.1, "DDR SDRAM Initialization
Sequence," details.
0 - Reserved
1 - The address and command are sent to the DDR SDRAMs source
synchronously.
In addition, Freescale application note AN2805 is also very clear that
this bit must be set.
This patch reverts a change introduced by commit
457caecdbc.
Testing Done:
Compiled targets CONFIG_TARGET_MPC8555CDS and CONFIG_TARGET_MPC8541CDS
and inspected the generated assembly code to verify the SS_EN bit was being
set. There is one extra instruction emitted:
fff9b774: 65 29 80 00 oris r9,r9,32768
Compiled the CONFIG_TARGET_MPC8548CDS target and verified that no
additional instructions were emitted related to this patch.
