[Linux-stable-mirror] Patch "ARM: OMAP1: DMA: Correct the number of logical channels" has been added to the 4.4-stable tree

If either uartclk or baud are 0, avoid calculating and setting a divisor based on them since the output will almost certainly be garbage. This also allows platforms such as the MIPS generic kernel, which has no way to know a valid BASE_BASE for the board it is actually booted on at compile time, to set BASE_BAUD to 0 and avoid early_8250 setting a bad divisor. This fixes a regression caused by commit 31cb9a8575ca ("earlycon: initialise baud field of earlycon device structure"), which changed the behavior of of_setup_earlycon such that it sets a baud rate in the earlycon structure where previously it was left as 0. All boards supported by the MIPS generic kernel started outputting garbage from the boot console due to an incorrect divisor being set.

Add a custom serial.h header for MIPS, allowing platforms to override the asm-generic version if required. The generic platform uses this header to set BASE_BAUD to 0. The generic platform supports multiple boards, which may have different UART clocks. Also one of the boards supported is the Boston FPGA board, where the UART clock depends on the loaded FPGA bitfile. As such there is no way that the generic kernel can set a compile time default BASE_BAUD. Commit 31cb9a8575ca ("earlycon: initialise baud field of earlycon device structure") changed the behavior of of_setup_earlycon such that any baud rate set in the device tree is now set in the earlycon structure. The UART driver will then calculate a divisor based on BASE_BAUD and set it. With MIPS generic kernels this resulted in garbage output due to the incorrect uart clock rate being used to calculate a divisor. This commit, combined with "serial: 8250_early: Only set divisor if valid clk & baud" prevents the earlycon code setting a bad divisor and restores earlycon output.
