after commit 4ab3817ff16a ("clk: fixed-rate: Enable DM_FLAG_PRE_RELOC flag")
Cubieboard7 (based on actions S700 SoC) fails to boot.
It is due to the fact that the default value of CONFIG_SYS_MALLOC_F_LEN (0x400)
would not provide enough memory for clock device to probe (before relocation)
well.
This commit fixes it, by increasing SYS_MALLOC_F_LEN to value 0x2000.

Xen is a virtual machine monitor (VMM) or a type-1 hypervisor with support
|
|
for para-virtualization. Xen can organize the safe execution of several
|
|
virtual machines on the same physical system with performance close to
|
|
native. It is used as the basis for a number of different commercial and
|
|
open source applications, such as: server virtualization, Infrastructure
|
|
as a Service (IaaS), desktop virtualization, security applications,
|
|
embedded and hardware appliances.
|
|
Xen has a special VM called Domain-0 that runs the Dom0 kernel and allows
|
|
Xen to use the device drivers for the Domain-0 kernel by default.

This setting is enabled by default. The reserved malloc

memory is initialized with zeros, so first malloc calls

It is recommended to disable it, when CONFIG_SYS_MALLOC_LEN

value, has more than few MiB, e.g. when uses bzip2 or bmp logo.
|

Then the boot time can be significantly reduced.
