In loongarch_cpu_class_by_name(char *cpu_model) function,
the argument cpu_model already has the suffix '-loongarch-cpu',
so we should remove the LOONGARCH_CPU_TYPE_NAME(cpu_model) macro.
And add the assertion that 'cpu_model' resolves to a class of the

Fix such errors:
1. We should not use 'unsigned long' type as argument when we use
find_first_bit(), and we use ctz64() to replace find_first_bit()
to fix this bug.
2. It is not standard to use '1ULL << irq' to generate a irq mask.
So, we replace it with 'MAKE_64BIT_MASK(irq, 1)'.

Our sensor test requires both reading and writing from a sensor's
QOM property. So we need to make the input of ADC module R/W instead
of write only for that to work.

We allow at24c_eeprom_init to take a I2CBus* as parameter. This allows
us to attach an EEPROM device behind an I2C mux which is not
possible with the old method.

Originally we read in from SMBus when RXF_STS is cleared. However,
the driver clears RXF_STS before setting RXF_CTL, causing the SM bus
module to read incorrect amount of bytes in FIFO mode when the number
of bytes read changed. This patch fixes this issue.

This type is used to represent block devs that are not suitable to
be represented by other existing types.
A sample use is to represent an at24c eeprom device defined in
hw/nvram/eeprom_at24c.c. The block device can be used to contain the
content of the said eeprom device.

When using "-machine none", env->tb_env is not allocated, causing the
segmentation fault reported in issue #85 (launchpad bug #811683). To
avoid this problem, check if the pointer != NULL before calling the
methods to print TBU/TBL/DECR.

Future code needs to call it from vhost_svq_add.

The Cortex-R52 has a 2 stage MPU translation process but doesn't have the
FEAT_S2FWB feature. This makes it neccessary to allow for the old cache
attribut combination.
This is facilitated by changing the control path of combine_cacheattrs instead
of failing if the second ca

These patches add the ARM Cortex-R52. The biggest addition is
an implementation of the armv8-r MPU.
The last patch adds a machine that combines the new core with
an UART and a GIC. This machine can run many samples of
the Zephyr OS.
