2021-02-02common: Drop asm/global_data.h from common headerSimon Glass1-0/+1
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass1-1/+1
This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-10-22serial: serial_xen: add DEBUG_UART supportAKASHI Takahiro1-0/+20
By using a hypervisor call, we can implement DEBUG_UART on xen. This will allow us to see messages even earlier than serial_init(). Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org>
2020-10-22serial: serial_xen: print U-Boot banner and othersAKASHI Takahiro1-2/+0
At present, DM_FLAG_PRE_RELOC is set only if !OF_CONTROL. It doesn't make sense for this para-virtualized driver.

2020-08-14serial: serial_xen: Add Xen PV serial driverPeng Fan1-0/+182
Add support for Xen para-virtualized serial driver. This driver fully supports serial console for the virtual machine. Please note that as the driver is initialized late, so no banner nor memory size is visible.
