[PATCH 2/3] spi: stm32: qspi: Clamp stm32_qspi_get_mode() output to CCR_BUSWIDTH_4

by patrice.chotard＠foss.st.com

From: Patrice Chotard <patrice.chotard(a)foss.st.com> In case usage of OCTAL mode, buswidth parameter can take the value 8. As return value of stm32_qspi_get_mode() is used to configure fields of CCR registers that are 2 bits only (fields IMODE, ADMODE, ADSIZE, DMODE), clamp return value of stm32_qspi_get_mode() to 4.

SMN accesses are done indirectly through an index/data pair in PCI config space. The PCI config access may fail and return an error code. This would prevent the "read" value from being updated.

Most systems will return 0 for SMN addresses that are not accessible. This is in line with AMD convention that unavailable registers are Read-as-Zero/Writes-Ignored. However, some systems will return a "PCI Error Response" instead. This value, along with an error code of 0 from the PCI config access, will confuse callers of the amd_smn_read() function.

This page overlaps with PTR_ERR, so that shouldn't happen. There is already some code to ensure memblock won't allocate the last page. However, buddy allocator is left unchecked.
